| Summary | Desktop freezes often when KDE starts compositing or mplayer GL window changes |
| Severity | major |
| Classification | Unclassified |
| OS | Linux (All) |

| Product | DRI |
When I turn on KDE compositing the desktop freezes more often than not. These freezes can also be provoked when configuring mplayer for GL output and opening a video file. If that alone is not enough, just change repeatedly from window to fullscreen and back. Attaching Xorg.0.log and dmesg of such a crash. I can reboot the system cleanly using alt+sysrq+r and ctrl+alt+del but any attempts to get a nice backtrace of the X server with gdb failed due to the process hanging in kernel space. Hardware: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Curacao XT [Radeon R9 270X] Running: kernel 3.14, libdrm2-2.4.99~git20140411-1.1, xorg-x11-server-7.6_1.15.99.902-306.1 Mesa-10.2~git20140411-5.1 llvm-r600-3.5~svn20140408-1.1.x86_64 openSUSE 13.1 Downgrading components to openSUSE 13.1 stock versions did not help except for downgrading the kernel to 3.11.
