Sentry Crash Report:

Description Bobby Wibowo 2019-11-10 08:53:40 UTC 
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
