[solved] ATI OpenGL application with wine distorts screen

hackerError · Last edited by hackerError on Mon Nov 17, 2008 8:30 pm; edited 1 time in total

Hello,

I am trying to run a game using wine, and when the game loads the screen becomes distorted. The screen seems to split in half and repeat everything on both halves of the screen, I can somewhat see what's going on on both sides but text is unreadable and there are other visual distortions.

Lets fix it!

Oddly as a test I just emerged neverball and it can run fine in fullscreen mode, maybe this is a wine issue.

while the screen is doing the split thing, is there scrambled pixels everywhere?

i'd try downgrading ati-drivers... i had the same issue with VT switching between X sessions. it makes the whole session unusable until i reboot. not sure if the our issues are related.

cheers

Same Problem here!!
I have scrambled pixels all over my desktop even when I start firefox.
I then only can close the x session and restart it again.
Has it something to do with wine and the ati drivers?

Please help!!

This is a known bug, somenthing about resolution being dividable by 64... It was introduced after 8-5, so if you install 8-5 you should be fine.
Another workaround is to "eselect opengl set xorg-x11" after you installed a driver >8-5. For some reason this does not happen when using x11's libgl.so. This results in a slight performace-loss, but nothing big.
There's also one more workaround, something about adding a virtual screen 1 pixel higher than you're real one to your xorg.conf or something. I didn't try this though (I'm running xf86-video-ati currently).

eselect opengl set xorg-x11
fixed the issue for me for now. Never again will I use an ATI card, they're too much of a pain in my ass.
For posterity that searches, this issue is also identified as " checkerboard of doom "

Thanks.
