I have a flat panel 1280x1024 connected via DVI. Everything is fine as long as the resolution is 1280x1024. However, when I start a game that tries to switch the resolution to different or just press Ctrl-Alt-+, the screen switches the resolution but there is major jittering in the middle part of the screen. When I connect the flat panel via the analog cable, all resolutions work fine.
The graphics card is ATI8500LE- if that matters.
can you try the displaypriority options and see if they help? See the radeon man page for more.
Created attachment 2033 [details] Xorg.log with DisplayPriority HIGH No, it does not help - the tearing is still there. I attach Xorg.log with DisplayPriority set to HIGH - I hope it will provide some hints.
Compare #1724.
Does #1129 or http://suif.stanford.edu/~csapuntz/rv280-linux-dvi.html help you at all?
