           Summary: Kwin desktop cube crashes when I press Ctrl+F11
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: ryanfarmer at gmx.co.uk


When I press Ctrl+F11 to enter the kwin desktop cube, kwin crashes and
immediately recovers giving the information at the bottom of this report.

Also, when I select the option to automatically rotate the cube when dragging a
window to a screen edge, the cube sort of half-rotates and then sticks there.

This has been an issue with recent git versions of Mesa/r600g for probably a
week, I just haven't gotten around to reporting it.

Currently I am using the X/Mesa stack from the Ubuntu Xorg-Edgers PPA on
Kubuntu 11.04 with KDE 4.6.2. I have a custom kernel which is currently based
on Linux 2.6.39-rc5-git2, it has the latest drm-next patches added to it.
