Description Pierre Ossman 2007-12-30 11:16:56 UTC
When I'm using my Geforce 7300 GT and a DVI monitor, the bottom 10 lines or so occasionally fill up with garbage. The data comes from other parts of the screen, so it's not completely random but rather some kind of transfer error.

I'm using the RandR 1.2 code as the DVI port refuses to work correctly with my monitor with the old stuff.

Please try again and provide an xlog of your attempt.
Comment 2 Pierre Ossman 2007-12-31 06:03:25 UTC
Have you committed some changes? Otherwise it's the same Xorg.0.log as in bug 13864.

Update from discussion on IRC:

The problem only appears with a large maximum framebuffer (2720x768) instead of letting X choose a maximum equal to the panel size (1360x768). Maarten constructed a patch that solved the issue.
Comment 9 Pierre Ossman 2008-01-05 17:56:31 UTC
I've tested the code committed and it works nicely. Feel free to close.
