-- Information about the crash:
- What I was doing when the application crashed:
I closed all applications as normal and suspended the PC.   On wake, the error occured.  It should be noted that this error occurs from time to time.  Other users have reported it.  It may be connected to the GPU (in this case, GTX 1070).  If there is a solution, I'm all ears.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
