           Summary: r300 performance is slower on sleep resume
           Product: Mesa
           Version: 7.11
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: nekohayo@gmail.com


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.

Demonstration: http://jeff.ecchi.ca/public/gnome-shell-657664.webm

Reminds me of bug 39714.

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

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.

files requested in bug 39714 comment 4

/sys/kernel/debug/dri/0/radeon_*_mm
/proc/mtrr

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.
