white box randomly shows up at top left corner blocking applications from using stuff under it

here's another computer of mine that it happened on. nvidia graphics on this one.

Status changed to 'Confirmed' because the bug affects multiple users.

I've also found when this happens that I can issue a "killall compiz" from a terminal and the white boxes go away. Compiz automatically respawns and the desktop is usable again.

try disabling the panel transparency and see if that makes a difference.

I think this is the same problem also happend while using chrome, but it covered nearly the complete display, the area below it is usable but you can't see what you are doing.
On pressing Super+S the workspace switcher showed, but every workspace had the white box (sorry forgot to make a screenshot)
Tried unity --replace via alt+f2 it resulted in some flashes, afterwards the desktop was completely unsuable, the launcher didn't react, alt+tab worked, but every window fas filled with the background of the desktop

this happens to me too... the box appear in the upper left corner of the screen and goes away only with killall compiz

Same thing here, I use chrome a lot. I _think_ it might be the HTML5 notifications (like from gmail)

yes, i discovered too that it is related to desktop notifications, especially when the browser is not focused and a notification pops-up... what is to be done? i dont like firefox html5 not via adddon because it is blended with ubuntu notifications..and i want those separate, in the lower right corner and clickable

Yup, definitely desktop notifications in chrome cause it. I just had 5 emails come in back to back and noticed the white box pop up when the notifications came up.

@omer:
When it last happened I opened up ccsm and turned off panel opacity (set it back to it's defaults). No difference. The box still remained.

Could anyone please point a few steps to reproduce the problem so we can update the bug description and then add it to the Unity priority list.

this isn't 100% reproducible, but pretty close:

-open up chromium
-go to google music (google.com/music)
-start playing a song
-the chromium pop-up will show displaying the artist and track name (i think default is for it to pop-up in the bottom right)
-you'll see a small opaque white box show in the top left

as stated previously, restarting compiz makes the white box go away

I haven't yet reproduced it yet from this site, but it would probably be one of the easiest ways to force notification pop ups to come up:

http://www.html5rocks.com/en/tutorials/notifications/quick/

I've tried Sam Mackness's steps to reproduce the bug, but I wasn't successful in doing so...

I think the white box is definitely caused by the chrome notifications, but I still can't see a pattern. I get popup's in the lower right corner as part of the Google Dictionary Extension and I believe the last time one popped up it also made the white box appear on the upper left of my screen. I then restarted unity (the box disappeared) and tried to reproduce by sending emails to my Gmail account which I opened on my chrome browser on the affected machine. I saw all Email notifications pop up, but even after about 20 or so emails still no white box appeared. Maybe because I had already restarted unity once (after the white box initially appeared after the Dictionary pop up) ???

Did some more testing to see if the white box is caused by the Gmail Desktop Notifications. I rebooted and logged out/in a couple of times and each time after having logged in again, I started google chrome and sent an Email to myself (via a second device) to cause a pop up. But no white box showed up!

I'm still getting this in oneiric. In fact it happened today and appeared to be caused by Chrome. Though I personally suspect a window leak of sorts in Nux or Unity, maybe Compiz.

I'm pretty sure I've had this problem since natty though (all versions of Unity).

Well, I do run chrome a lot, so it does overlap. istr chrome does
create some (should be) unmapped windows for its own purposes and
perhaps that's not what unity's expecting. However, it persists even
after exiting chrome.

Just happened again. When I opened Google Calendar in Chrome. The white window was the same size and shape as the client area of the Chrome window. Just shifted to x=0 and of course over the top of everything else.

Status changed to 'Confirmed' because the bug affects multiple users.

I get what might be a variant of this bug. A white window or box appears covering the page display area but none of the UI in chromium.

My problem seems unrelated to either notifications or Flash; for example, it can appear when using the "Open Image in New Tab" context menu item. It always appears on the initial page load.

Despite the white box, I can Alt+Click to drag windows out of the covered area and interact with things underneath; they're just not visible.

Logging out, then back in is the only way to make it disappear.

Attaching two screenshots.

Two more notes:
—I have two machines with ATI graphics cards, and only the one with fglrx enabled is displaying this behaviour.
—Contrary to #17, I've only seen this since upgrading to precise beta.

I have two PCs with Nvidia GPUs, both having the same issue. Only in precise beta.

I have this issue with NVidia (binary driver), ATI (fglrx) and Intel Sandy Bridge as well, on 3 different machines, with Ubuntu 11.10. I always used Chrome/Chromium when the white box showed up but that may have been just a coincidence.

I have this on intel arrandale, so I don't think it's connected to the
graphics driver. I do use Chrome, so that does seem to be the common
factor.

All my windows have shadows. Now the computer has been on for a couple of days. It seems that is not only one white rectangle, but there are many, as the border became black, the same that happens whenever I open many windows of the same size in the same position.

I use chrome, and I'm guessing it's something related to it. My guess is google notifications. Whenever I use my computer without opening google chrome, the white box never appears (ie: my laptop). It has the same width as the google notification message box.

Confirmed!

Steps to reproduce:

1- Turn on ubuntu 12.04
2- Use chrome with gtalk notifications on.
3- Tell someone to chat to you in a few seconds.
4- Switch focus and wait for that someone's reply.

For me this started with 12.04. I can reproduce the small upper-left-corner boxes as described in #14. I also have the #7 boxes randomly and can not associate them with something specific. I use chromium a lot. I have set some compiz custom settings (via ccsm) but have not yet tried to isolate it. Logout/login fixes it, killall compiz fixes it as well.

another way to reproduce: use ANY website that sends some sort of html 5 desktop notifications.. i for one dont use gmail or gtalk, but am affected and stay all day long with that white box because i use woopra (like clicky but free) and i have desktop notifications enabled. for that site in order to receive real-time notifications about visitors.. i gave up clearing the white box with the killall compiz because regardless if in 1-2 minutes or in 15 minutes, the white box always reappers due to constant notifications.

I have hit this bug a few times on my machine, when I type "xlsclients -al" I see the following in addition to what I had running before the white box appeared on the screen:

Window 0x3e00001:
  Machine: x
  Name: exe
  Icon Name: exe
  Command: exe
  Instance/Class: exe/Exe
Window 0x4000001:
  Machine: x
  Name: exe
  Icon Name: exe
  Command: exe
  Instance/Class: exe/Exe
Window 0x4200001:
  Machine: x
  Name: exe
  Icon Name: exe
  Command: exe
  Instance/Class: exe/Exe

Tried to xkill by id, but the window still persists.

Chris, All,
I believe the "exe" windows are embedded windows from browser plugins. So with flash for example they are probably created by the process I can see:
/opt/google/chrome/chrome --type=plugin --plugin-path=/usr/lib/adobe-flashplugin/libflashplayer.so

This also supports smspillaz' theory (he told me) that it's to do with reparenting of X windows. I imagine any window created by a plugin process gets reparented into the main browser window. Looking at "xwininfo -all" seems to support this.

Does anyone find any part of their web pages/apps are missing/broken in their chrome window when the white box appears?

Note, that the latest compiz in Precise is 0.9.7.4-0ubuntu2, so you need to do something like this after adding and updating:

    sudo apt-get install compiz=0.9.7.4-0ubuntu2~bzr3086~precise1

to use the right compiz. :-)

I'm sorry, but I have to attache my xwininfo. :-(

Did you maybe not enable the animations plugin?

If Sam's fix in 0.9.7.6 is working then this needs to be marked fix released in 0.9.7.6.

FWIW: I'm not able to reproduce this with a virtual machine at all (known broken Compiz version, not the PPA one).

For what it's worth, I don't think this is fixed still. I believe I tried
Sam's latest PPA and still got the issue. I will update again and give it
another go, though, to see if it is fixed.

its not chromium bug. appeared without chromium. and as usual "killall -HUP compiz" helps

Just as a quick "me too" here.. I'm running precise with current updates with focus animations set to None and I just had the white box occur.

I have a gmail notifier installed that lets me see message counts and click through to chrome+gmail from the messaging menu. When I did that and a new chrome tab opened (on my right monitor) I got a giant white box the same size as the chrome tab on my left monitor.

same as #121.

I don't know if it has something to do with JavaScript popups generated by Chromium extensions like the one I use :
Mail Checker Plus for Gmail & Facebook Notifier. It happened to me several times, when a new popup appears (Gmail or Facebook ).
The bug applies to Chromium and Google Chrome in my case.
Let's add that even disabling these extensions, browsing websites with Flash content that prompt the user to interact with some popups, may trigger the white box.

The size of the white box I get, is different every time, from a very small rectangle to a whole screen blank box.

I also believe it is a compiz Issue, well at least, the way Compiz handles these popups.
Running Precise updated.

Jason, Sam's *potential* fix will be released in compiz 0.9.7.6. Please double check when you get that update. It's not a definite fix, but feedback about compiz 0.9.7.6 would be most valuable.

running the machine for about a week, received more than 5000 pop-ups in this time, and no white box.. in my case the only permanent solution was to disable the animations plugin altogether... with focus animation set to "none" a white box still pop-ups after several hours, although much much rare than in the case when it`s set to "n/a" or "fade"..

Not sure if I applied the potential fix correctly. I added the ppa, performed an update, and installed the new compiz packages from the update. I just saw the white-box again (maybe 14-15 hours after doing the upgrade). I attached my xwininfo in case that helps.

Just an FYI. I still get this with latest compiz and unity (compiz 0.9.7.6 and unity 5.10 candidate from unity-team/ppa). Turning off animations to test that out....

Fix committed into lp:compiz-animation-plugin at revision 397

Fix committed into lp:compiz-plugins-main at revision 27

Seems to be fixed here. All that's left is a white window showing up for a split second every now and then. Less frequently and far better than a stuck window. :-)

Indeed.

Noting here that the white window will always appear for a split second because that is what chromium is doing.

From what I've read in the comments, it looks like this is similar to a problem that arose years ago with the "system tray" as it was called. (The name "system tray" came from the "systray.exe" process on MS Windows which provided some icons for what was officially known as the notification area.)

The old system tray in GNOME, following KDE's model, would occasionally fail to display icons in the tray; instead they were framed by the window manager—sawfish or sawmill at the time. It didn't always happen. It was unpredictable.

The root of the problem was a race condition. KDE's protocol required a commitment (unspecified, as I recall) from the window manager to not try to manage windows somehow marked for the system tray. Applications would map the window, the window manager would ignore it, and the system tray would reparent it. GNOME's implementation did not include the window manager commitment. Applications would map the window and both the window manager and the system tray would try to reparent it. The outcome was determined by whichever process won the race to reparent.

The subsequent freedesktop.org system tray protocol eliminated the race condition by not mapping the window destined for it before the reparenting was complete. Instead of mapping, clients were expected to send a ClientMessage to the tray. After that the XEMBED protocol took over.

It sounds like chromium is mapping when it should not be mapping. Searching through the code right now I've seen at least two places where they call XMapWindow during initialization of some objects. I must be missing something because I haven't found embedding. (But I just started minutes ago.)

I backported the patch to my oneiric ppa and the fix works: using the test html page I attached earlier I can not reproduce the white box. As Sam said sometimes it does show up for a split second at 0,0 (top left corner) but it disappears as it should. Well done!

after compiz upgrade (today) i don't get any white stripe when using chrome and gmail chat.

Still the focus effect is set to "N/A", at least in upgraded Ubuntus.

For the record, it appears that the Ubuntu Precise build failed: https://launchpad.net/ubuntu/precise/+source/compiz/1:0.9.7.6-0ubuntu1

ping? this is such a critical issue, and we would like to be able to test it before precise launches.

Thomas, the new compiz is in precise, you should be able to test from there or did I overlook something?

The new fix is in compiz 0.9.7.6, which was released just hours ago for Ubuntu 12.04. I hope it works for everyone.

Correction: The real fix is in compiz-plugins-main 1:0.9.7.0~bzr19-0ubuntu10

The build failed, did it not?

seems not?

We've got it now, and reports are coming in from our users that they are no
longer seeing the white boxes. Good news indeed, and thanks!

Yep. Has happened here twice so far. Both times after opening a new window in Chrome.

I find that typing compiz --replace in terminal gets rid of it. but that's only a temporary fix...

It just happened again to me this morning When trying to open chrome and visit a G+ hangout. apt-cache says I have 0.9.7.6:

bladernr@klaatu:~$ apt-cache policy compiz
compiz:
  Installed: 1:0.9.7.6-0ubuntu1
  Candidate: 1:0.9.7.6-0ubuntu1
  Version table:
 *** 1:0.9.7.6-0ubuntu1 0
        500 http://us.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
        100 /var/lib/dpkg/status

Compiz and compiz-plugins-main are different packages with separate
versioning.

What version of compiz-plugins-main do you have, and when did you last log
in?

compiz-plugins-main:
  Installed: 1:0.9.7.0~bzr19-0ubuntu10
  Candidate: 1:0.9.7.0~bzr19-0ubuntu10

My last login, at this point, was after rebooting. Something actually removed unity from my system. I don't know if it was a failed update or what, but when I got the "White Box of Doom" ;-) I restarted X only to get a background and none of the unity stuff (no bar, no launcher, nada.

Doing some investigating and I discovered that unity was not installed. I was able to re-install manually and reboot though :) I'm gonna blame a borked update on that one. or just the fact that my computer is an Alienware, so maybe there was some unity abduction and probing going on...

IN any case, prior to that I had not logged on in a few days, I tend to boot this machine and just let it run.

I've not been able to reproduce this problem since I installed some updates last week. Before that time I would experience the white box several times per day.

Fix released in Compiz Main Plugins 0.9.7.2

I'm still having this bug, with compiz 0.9.7.8-0ubuntu1.4.
Sometimes, if chrome is used, animations are played in the rectangular area on the top left corner. It not just a blank rectangle. It's an area where animations (from pages openned on chrome) are displayed.

Unable to capture the bug with printscreen. I'm uploading a real photo of the screen.

Linux beijing 3.2.0-32-generic-pae
nvidia-current 304.60-0ubuntu1~precise~xup2
compiz 0.9.7.8-0ubuntu1.4

Jorge,

Your photo shows you're experiencing a completely different bug. Regardless, please log a new bug using this command:
    ubuntu-bug compiz

Interestingly I encountered the same issue when working on Xmir rootless support this week. The bug there was that the compositing window manager (now Xmir itself) failed to notice that some sub-windows are flagged as un-viewable in the X server, so those odd little windows need to explicitly not be displayed (unless they are marked as viewable).
