Does not matter what decoration I choose. It happens everytime. All of the windows are functional just without a border or title bar. Sometimes using "kwin --replace" will correct the issue while sometimes logging out is the only way to fix it. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
