And after crash compositing state goes disable
unfortunately the backtrace lacks important information, so all one can see is that the segfault happens from a mesa/gl driver call. compositing is disabled to prevent further crashes. please read here on how to create useful backtraces and update the report, thanks. (for suse install the -debuginfo packages) in general: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and for openSuSE in particular: http://en.opensuse.org/Bugs:An_application_crashed
most likely a driver bug - top most item is libGL. But without a proper backtrace we can't say anything
