--- Comment #1 from David "okias" Heidelberger david.heidelberger@ixit.cz --- now it flickers for even GLX (git does that since 2 days circa)

--- Comment #4 from David "okias" Heidelberger david.heidelberger@ixit.cz --- Addional information:
So, in case non-broken mesa. It need to initialize GLX, then EGL render correctly. It work with broken mesa correctly, when glxgears was started with non-broken mesa which set something to card (registers?) corectly.

--- Comment #5 from David "okias" Heidelberger david.heidelberger@ixit.cz --- well, now it seems is not working with revision where it worked well. Seems that it worked was something random. I'll try downgrade to previous 3.9.1 kernel and if it'll be ok.

--- Comment #6 from David "okias" Heidelberger david.heidelberger@ixit.cz --- so tested range: kernel 3.9.1 - 3.11.0 mesa 2013-09-05 - today could it be xf86-video-ati? Why it is broken randomly :/

--- Comment #7 from Samuel Sieb samuel@sieb.net --- The screenshot URLS from the summary are not accessible now, but the description matches what I'm seeing. I have a laptop with RS690M (X1200) video and gnome-shell has flickering triangles everywhere. The application windows are ok, Logging out which restarts the X server usually fixes the problem. This is with Fedora 20. I tested with a Fedora 19 live system and there was no problem. I will attach new screenshots.

--- Comment #11 from mike@mgoodwin.net --- I've seen elsewhere and confirmed for myself (I'm reviving an old laptop today) that you need to use EXA acceleration and add "EXAPixmaps" "on" in the Devices section.
Option "AccelMethod" "EXA" Option "EXAPixmaps" "on"
and the problem disappears. Don't even attempt to use glamor, it doesn't work.
