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@lists.freedesktop.org ReportedBy: bio_tube@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:
