New crash information added by DrKonqi

kwin_x11 (5.17.5) using Qt 5.13.2

- What I was doing when the application crashed:

I scrolled my mouse wheel over the task manager

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

#6  0x00007fb41a8e99cd in  () at /usr/lib64/opengl/nvidia/lib/libGL.so.1

It's crashing somewhere in the Nvidia driver. Please report this issue to the Nvidia folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-unix-graphics/linux/

It would be helpful to the Nvidia developers if you could run nvidia-bug-report.sh and attach the resulting file in your report.
