Created attachment 100256 [details] Debug output of kwin
No. Please install kwin-dbg, trigger the crash (run the fullscreen game) and attach the new developer information from the crash dialog (just what you posted before, but now it will contain more information) (The latest attachment shows gdb attached to kwin, there's no segfault occurred and notably no trace contained.)
