First page disappears, other pages shift

Happens here too.

Moreover, when it happens, my first page simply disappears. Marking high priority because of that.

According to duplicate bug 956068, this happens after installing an app.

I have this bug after updating packages but not installing any new ones

I have this for removing and updating. installing was a mistake, I was installing apps and updating at the same time :p.

i think i found a fix but it will need glib and i don't know how to add --pkg flags to cmake.
the fix is: remove the following:

                categories = app_system.get_categories ();
                apps = app_system.get_apps ();

                populate_grid_view ();

and add this:

spawn_command_line_async ("killall slingshot");

could someone please explain how to add --pkg flags to cmake or try this themselves?

All is in CMakeLists.txt files. But you don't need to add glib, it is
added since gtk (and granite, and everything related to vala (if we
don't count sdl)).

I'm not sure doing a "killall slingshot" is really the right way to do
it, we should be able to make a clean reloading/adding without having to
close the process.

Yeah, I'm with Lucas; making Slingshot commit suicide to workaround a legit
bug just seems hacky. ;)

I think it will work pretty well. It means you can replace 3 lines of code for 1 line of code and fix a bug. I think there aren't many other ways to fix this bug cause the code there is now already does reload it in the "right" way, and that doesn't seem to work :p.

Do you already have this bug? For me it is fixed

Haven't been noticing it lately, let's see if anybody confirms it now

I have to confirm this bug again. Installing a new app, first page disappears

This bug is still actually.

I can confirm, bug is still present.
In the upcoming days I'm gonna take a look at it (even though I'm quite busy, likel from Saturday). If there's a simple fix let's use it, which is the best. But if we cannot find any way to fix it (and seems as illogical as the close-on-focus-out bug) I propose to simply use Tim's fix for Luna and find a proper solution for L+1.

This wasn't an issue in Clutter-based Slingshot. Maybe we should revive that branch?

Clutter Slingshot has a plethora of other rather show-stopping bugs. If a proper fix isn't simple, I don't think it's entirely evil to use Tim's fix as a temporary solution.

We need to be operating as if we have very limited resources and we're trying to make a release before Summer has come and gone. There will be plenty of time for major changes in the Luna +1 cycle, let's just focus on making things work for now.

I still get this bug fairly reliably in version 0.6-0~r221+pkg10~precise1
It's not related to software updates this time - all I have to do is to scroll back and forth quickly.

Shnatsel, I can't reproduc it, can you please make a screencast?

Here you go. Took a long time to get it this time.

I also got it to shift by just one icon row on a slow machine.

I tried everything but I can't reproduce it on my machine. I pushed lp:~voluntatefaber/slingshot/page-shifting with some more checking before moving a page. Can you please test and tell me if still happens?

Thanks! I cannot build the merge of this branch with lp:slingshot though, here's the error I get:

/home/precise/sandbox/slingshot/src/SlingshotView.vala:295.17-295.82: error: 1 extra arguments for `void Granite.Widgets.PopOver.move_to_coords (int x, int y)'
                move_to_coords (monitor_dimensions.x, monitor_dimensions.y, false); // this would be coordinates 0,0 on the screen
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

That's because of a recent change in granite. But lp:~voluntatefaber/slingshot/page-shifting should build fine with older granite.

Happens again in version 0.6+r283-0+pkg13~precise1 and possibly a few earlier ones

Shoot! I wanted to release Slingshot by tomorrow but if this is back in action we can't! And not having a way to reproduce it make tracking it even harder!

After some testing, I saw it's a bug introduced with the not-too tested gmenu-3 revision. I'm switching back to the old gmenu for beta1 and hope to find a solution with Ricotz by beta2 or luna release.

I could reproduce this bug in the last build from elementary daily doing the following:
  1. Start to install an app that puts an icon in slingshot.
  2. Open slingshot and start switching pages.
  3. Just before the application ends installing slingshot has all the icons shifted.
I attach a screencast.
Hope this helps.

I'm reopening the bug based on Shanti's comment.
