Application window goes blank when restoring (maximizing) from minimized state

[Ivan Katanović]

Steps to reproduce bug:
1. Open any app and maximize it
2. Minimize it with minimize button, wait for animation to finish. Click on launcher to restore that app. Everithing is OK
3 Minimize app and while minimize animation lasts click on the launcher to restore app. Window restores to maximized state but is blank (white).

You can return contents of window by:

1. Double clicking on panel
2. By repeating action which makes things disappear (step 3 from above).

I have duration of minimize and maximize animations set to 400 ms so it's easier to reproduce bug if animations last longer.
After reproducing bug and closing that window (or soon after) compiz often crashes and I get this bug report:

In the attatchment is clip which shows all described above (sorry for bad quality, but you'll get the picture).

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

[Ngassam Nkwenga (cyrildz)]

I'm experimenting this bug right now since I started using the Unity-Staging PPA

[digio.space (digiospace)]

I recently started experiencing this bug as well. Using Nvidia graphics card with latest updates from the Ubuntu X-team

[Sven Romeike (lun4tic)]

I also have this and can reproduce it:

1) start application1
2) switch virtual desktops
3) start application2
4) switch back to application1
5) maximize application1
6) minimize application1
7) switch virtual Desktops to application2
8) click the launcher icon of application1

the Window of application1 should be and stay all white until you resize or unmaximize the window.
