Description Jean-François Fortin Tam 2011-08-30 09:22:20 UTC
I have the following on a Thinkpad T43p:

jeff@kuze:~$ glxinfo |grep OpenGL
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV380
OpenGL version string: 2.1 Mesa 7.11
OpenGL shading language version string: 1.20
OpenGL extensions:

When starting a fresh boot with a couple of windows open, gnome shell is fluid. Keeping the same amount of windows open, suspending then resuming, the performance when toggling the overview mode seems to have degraded significantly.

Reminds me of bug 39714.

Please attach the full Xorg.0.log and the output of dmesg and glxinfo.

As requested.
Comment 5 Michel Dänzer 2011-08-31 06:45:16 UTC
Please follow the same investigation steps as in bug 39714, e.g. see if restarting just gnome-shell restores full performance, and capture some files before and after suspend/resume.

But not /sys/kernel/debug/x86/pat_memtype_list, as the file was not present.

I have some doubts that maybe this might be unrelated to suspend/resume, but instead related to the amount of windows open and/or general bugs/corruption... I've noticed that after a short while (maybe after opening a couple of browser windows), not only does performance decrease a lot, but there are weird visual glitches: font glyphs missing, colors changing in Getting Things GNOME, text shadows or colors in various apps (gedit, browser windows) going black, scrollbars going black, etc.

Is it still a issue with current mesa and kernel ??
