--- Comment #7 from Kamil <redredempt...@protonmail.com> --- This time I pulled backtrace up upon the crash. (I let Kwin restart itself) Previously, I reproduced the bug, and then pulled backtrace up when Kwin was frozen. I've never done that before. If I still do it wrong, please put the record straight and tell me how it should be done.
