           Summary: VLC crashes on fullscreen with GLX output and
                    colortiling enabled
           Product: Mesa
           Version: 7.9
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: bio_tube at yahoo.com


It works in window mode, but it crashes the instant it switches to fullscreen,
giving the familiar "drmRadeonCmdBuffer: -22. Kernel failed to parse or
rejected command stream. See dmesg for more info."; I've checked and this isn't
fixed in master, either; r600g performs as expected, so this is definitely a
Mesa bug(I've already pulled the latest in the 7.9 branch). dmesg gives the
following:

[ 1953.411625] radeon 0000:02:00.0: r600_cs_track_validate_cb:220 cb height
(724) invalid
