--- Comment #2 from Dann <initial.d...@gmail.com> --- I tried to go through KCrash to add a comment but I got some permission / modify comment error, so here's the report (via web interface) In summary: using 5.14.1 qt libs and still seeing this issue. Application: kwin_x11 (5.18.4) (Compiled from sources) Qt Version: 5.14.1 Frameworks Version: 5.68.0 Operating System: Linux 4.14.173 x86_64 Windowing system: X11 Distribution: "Gentoo Base System release 2.6" -- Information about the crash: - What I was doing when the application crashed: Running slack video chat which constantly shuts off my compositor randomly, editing code on two vertically aligned monitors. What set it off, as it has before, was alt-tabbing. Since filing this bug, I've upgraded qt libs to 15.4.1 (with some -rN packages). This crash occurs whether slack runs or not. I get black flickering on some windows, but that may be related to mesa/nvidia as I'm stuck on the 390.xxx series and not compiling with libglvnd flag. - Unusual behavior I noticed: A short bit of lag before the crash occurs. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
