system information
I faced the same issue. It occurs after hour-two of painting session (sometimes
faster). I suspect the system uptime may affect how often it occurs. Long
uptime (few days) or if the system was suspended and it occurs more often. Also
probably the NVIDIA drivers could be the reason, because canvas doesn't appear
right (semitransparent/incomplete) after system suspend/resume and I had to
restart Krita.
On the current project it happened about 6-7 times and I had to re-draw some
parts again and again (quite annoying), though auto-save is set to 2 minutes..
GDB backtrace doesn't show somewhat useful:
