           Summary: DVI corruption with RandR 1.2
           Product: xorg
           Version: 7.3
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: drzeus-bugzilla-p3sGCRWkH8CeZLLa646FqQ@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


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.

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.
