           Summary: KMS, kernel, Second Monitor becomes complete blur when
                    loading fullscreen GL
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: highest
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: oyvinds at everdot.org


On affected system:

1. Load fullscreen OpenGL something which thinks fullscreen means both attached
monitors. This includes kwin and warzone.

2. Kernels 2.6.37-git15 2.6.38-rc1-git2 2.6.38-rc2-git7 show expected on first
monitor and complete blur on second monitor. Total messy blur. Everything works
perfectly with stable 2.6.37-gentoo kernel. I do not know what happened with
<=2.6.37-git15, but I do know 2.6.37-git15 kernels and later are defective.

It would be nice if someone could make two monitors work with OpenGL again
(working kwin is nice).
