Description Aleks 2013-10-11 18:01:36 UTC
Hi,

I try to run my Archlinux with Glamor acceleration on my RV670 card (AGP), but X server takes a (slight) high CPU usage (~15-18%, on Opteron 185 2600 MHz S939) when i activate it with xorg.conf. Revert back to EXA falls X CPU usage to < 5-6%. Moreover, with Glamor, some gtk2 applications have strong lag for example when i click on a menu in the menu bar, like Thunar, or, when i switch tabs of web pages in Midori. This is strange because i have no problem when i scroll web pages, all run smoothly (better performance than EXA). On other gtk2 applications i haven't this problem. Also, with Glamor enabled the XFCE logout dialog takes about a minute to be shown. Neither Xorg.log nor dmesg show anything about any bug (memory leak or other). X has never crashed.

Here some informations :
glxinfo > OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV670
OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.2.1
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)

uname > 3.11.4-1-ARCH #1 SMP PREEMPT Sat Oct 5 21:22:51 CEST 2013 x86_64 GNU/Linux

OK, on Libreoffice buttons are paint in black, and the application causes a high X cpu usage (~40 %). When i open a file in Calc, the system is slow down and is very near to hang up.

You should try current git glamor, it has some fixes and speedups.
Comment 3 Maks 2013-12-14 10:46:14 UTC
Exactly same problem with Mesa 10.0.1
