Bug Description
I have white rectangular on the top left of the screen. It is half of the screen wide and two icons in unity high. It is covering the icons and the destop. Print screen does not take the picture of it. I have it there for a week at least. It is not there from the start of session, but it shows up latter. I do not now why it shows. I was using chrome and update only.

About how long after the session start does the white box appear? Does logging out and logging back in make it go away? How about switching to a virtual terminal and back? (ctrl+alt+f2, ctrl+alt+f7)

Here's what I mentioned to Bryce about this issue in a comment on bug #933778 (a likely unrelated bug):
"I also noticed (and this is probably the topic for a new bug report), that a particular operation in Chromium caused a new window to appear, which is completely white, always on top, not associated with any application, and difficult/
Since that was written, I no longer see compiz using 24% CPU; it has fallen back to normal levels (about 2-5%).
Note that though this white window is always on top, it is not clickable; any mouse operations affect the window behind it (for example, I can select text in a browser window that is behind it and the cursor changes to the text select cursor when I hover over text in a window behind the white window).
As you can see, I was able to take screenshots of this issue. It seems that the white window is tied to all workspaces, but not to the X display itself (since showing the workspace switcher moves the white window onto each of the displayed workspaces; it does not keep the white window on top of the workspace switcher itself).
If you need any more info about this issue while it is still present, please let me know soon. I plan to logout and log back in by the end of today as it's impeding my workspace. The bug does not seem easy to reproduce; I haven't seen a new white window since I managed to create one yesterday. The steps for reproducing in the quoted section above are the best I have.

As a follow-up to my original summary of this issue, I noticed also that the white window appears in the lock screen as well. So it obscures the password entry box if that box decides to show up on the monitor where the white window is. Also, once the login screen "times out" (ie. goes back to a black screen), the white window remains on the screen, overtop of the otherwise black screen.

Fabio Marconi (fabiomarconi) wrote : | #54 |
Hello Denver
Sorry I was thinking to a something much more little: I want to know if with the bug in action, as Bryce suggest, pressing Ctrl+Alt+F2 ( to enter in tty mode) this window disappear and you have a black screen like the terminal. Press Ctrl+Alt+F7 to restore it.

Interesting, thanks for the pictures Denver. So, this is starting to look much like a compositing issue of some sort. Let's check a couple things to be sure:
First, try logging in to Unity2D and see if you can reproduce it there. If so, then also try Gnome Classic (No Effects) - install the 'gnome-panel' package and that should add this option to your login session.
If you find it only occurs in Unity, then it may be a mesa issue. I have a PPA with a mesa update we're currently testing, which fixes some random bugs on -intel. I suspect it won't fix this bug, but it's probably worth testing. Please install this PPA and see if it makes any difference: https:/

Hi Fabio,
The white window remains after switching to a virtual terminal (Ctrl-Alt-F3) then back to X (Ctrl-Alt-F7).

Denver Gingerich (denver-ossguy) wrote : | #57 |
Hi Bryce,
I can't reproduce this bug reliably at all so I'd prefer to try things with the existing white window that hasn't disappeared yet (but that I will be getting rid of this evening sometime, as it's getting in my way). But I can try those options you mentioned anyway and hope it reproduces itself.

Bryce Harrington (bryce) wrote : | #58 |
This is probably a dupe of bug #936758.
I'm growing more certain that updating to 8.0.1 via this PPA will resolve it:

Hi Bryce,
That is good to know. Are there anymore details I should retrieve/tests I should run before I logout/login and dist-upgrade to get the hopefully-fixed mesa package?
By the way, the mesa bug and this bug suggest the problem is in the Intel graphics driver somewhere. I'm not using Intel graphics at all; I'm instead using the radeon driver (with a Radeon HD 5000 series chip). Just thought I'd mention in case it's relevant.

Denver Gingerich (denver-ossguy) wrote : | #60 |
When I logged out of my account this morning, the white box disappeared (it was not present at the login screen). And when I logged back in, it was not present either. I'm upgrading now so hopefully some of the updates fix it. (Again, I've only seen it once in several days so it's very difficult to reproduce.)

Hello
looking at the attached screenshot I can see the shadow under the rectangle, so I think that is something other.
Can you drag it with Alt+left click ?

Hi Fabio,
I did not specifically try dragging it in that way before I closed it (by logging out). I suspect it would not have worked (the drag operation would have applied to the window behind it) because generally I was not able to interact with the white window itself (operations always applied to the window behind it, as if the white window wasn't there). It's possible that I dragged a window behind the white window using Alt+left click; I certainly never noticed a case where I used Alt+left click and happened to drag the white window.

Hi Bryce,
Yes, I just reproduced it with mesa 8.0.1. Here's some dpkg output from my system (I dist-upgraded around 6pm Eastern yesterday, 2012-03-06):

So I believe this issue still exists with mesa 8.0.1.
Fabio, I tried dragging with Alt-LeftClick and that drags the window behind the white window, not the white window itself (as I had expected). Everything else looks the same as before so I think there's no need to upload new screenshots.

Denver Gingerich (denver-ossguy) wrote : | #68 |
The issue I reported above happened with Chromium, just as before. I believe the sequence of events this time was: highlight text in address bar (via double-click), copy the text (via Ctrl-C), create a new tab (via Ctrl-T), paste the text (via Ctrl-V). I think that the box appeared at the moment I created the new tab, but I could be wrong.

Denver Gingerich (denver-ossguy) wrote : | #69 |
As before, the white box gets in my way a fair bit so I'm planning to get rid of it by tomorrow morning. So if you want me to perform any tests on it, please let me know soon.

Bryce Harrington (bryce) wrote : | #70 |
Alright, thanks for all the feedback. Given that the boxes go away when logged out, and that Denver is on -radeon whereas Andreas is -intel, it is likely sounding not to be a driver issue. It is probably compiz doing something wrong.
I see there are similar bugs against compiz, #940603 and #753606, but the symptoms differ, so not setting as dupe. (940603 is also against chromium, so may be pertinent)
