HD4770: Screen corruption and artefacts with the from-git graphical stack
I have had corruption problems with the open source driver for a few days now and it doesn't seem to go away.
Here is a video of the current state on my computer:
Do you guys have any idea of what's going on ?
Thanks a lot
Are you running openarena with LIBGL_ALWAYS_INDIRECT=yes ? It will look pretty bad if you don't right now...
Also, EXA DFS seems to have issues on some rv740s.
should fix any issues with the cursor or small pixmaps.
Thanks to both of you! It works quite well.
There are still some minor corruption problems when typing text for example but I can live with it
Perry3D: Did you activate Option "EXANoDownloadFromScreen" ?
It solved my problems and I no longer have this kind of corruption.
Yes, i already tried this option: no difference.
The corruptions appears when typing text, opening the gnome menu and some progress bars:
Yes, this is a known issue.

I'd just like to chime in and say that EXANoDownloadFromScreen fixed the pointer corruption issues I was having in Gnome as well (no compositing, Ubuntu 9.04 w/ git drm/mesa/xorg-driver).
My card is a Radeon HD 4770 on a Gigabyte 785G-based mATX motherboard.
I'm still getting glxgears corruption with both normal GL, and with LIBGB_ALWAYS_INDIRECT=1, but I won't be able to do much troubleshooting with that until after work probably.
