Application: kwin_x11 (5.10.4) Qt Version: 5.9.1 Frameworks Version: 5.36.0 Operating System: Linux 4.12.3-1-ARCH x86_64 Distribution: "Chakra" -- Information about the crash: - What I was doing when the application crashed: export DISPLAY:=":0" && Kwin_x11 --replace. This heps to resolve issue. - Unusual behavior I noticed: Crash happens every load on arch with last pkg base. Sometime kwin will load after about 40 sec. Sometimes after waiting kwin still not lauched. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
