application icons mangled after suspend

[Bogdan Butnaru]

Binary package hint: compiz

Hello! I'm running up-to-date Jaunty on a Dell Latitude D620, with an Intel graphics card (lshw calls it “Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller”).

After a suspend, the icons of programs that were running before are “mangled”, apparently replaced by random memory contents. This is apparent in how minimized applications are displayed in the shift switcher and the static application switcher. (I assume the same applies for the other switchers, but I don't use them.) Applications started after the resume have their correct icons. See the attached screen-shots for examples.

In the screen-shots, the icons that are displayed correctly belong to windows that I started after the resume. It's interesting that this is window-specific rather than application-specific. For example, in the first screen-shot, one Firefox window icon is shown correctly and one isn't; the correct one belongs to a Firefox window I opened after the resume, which is the same application/process as the incorrect one.

It's also noteworthy that the window list and window selector panel applets don't have this problem, i.e. they display the correct icons.

Thanks for your bug report. The symptoms provided indicate this is a problem with your video drivers and is being reassigned to the xorg package. For more information on problems with visual effects and video drivers see http://wiki.ubuntu.com/VisualEffects.

Hi bogdanb,

Thanks for including an image to demonstrate the issue. Could you also please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log or Xorg.0.log.old file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

I've added the lspci output.

The bad news is that I can't attach the Xorg.log file; the good news is that it's because I can't seem to reproduce the bug anymore :D

I don't use the laptop that often these days, so I can't tell which update fixed it. But it seems fixed: I tried to suspend several times, stress it with many windows and video, but it doesn't seem to happen anymore. I'll re-open the bug if this occurs again.

Great, thanks for letting us know
