Application: kwin_x11 (5.17.2) Qt Version: 5.13.1 Frameworks Version: 5.63.0 Operating System: Linux 5.0.0-32-generic x86_64 Distribution: KDE neon User Edition 5.17 -- Information about the crash: - What I was doing when the application crashed: I was on tty2, which was also running an X server, but using Nvidia GPU (tty1 is using Intel integrated graphics), assisted by this utility: https://github.com/Witko/nvidia-xrun. tty2 is using Openbox instead. I'll keep on seeing notifications about graphics being reset and whatnot everytime I switch to tty2 then back to tty1. If I recall correctly, this crash didn't use to happen in KDE neon 5.17.0 or 5.17.1. I can't make sense of the logs so I don't know what's up. On a side note, I'm not seeing any issues/errors on tty2 whenever I switch back to it, but always does when switching back to tty1. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
