GPU crash dump saved to /sys/class/drm/card0/error

I see others with same issues but doing as instructed by error message:

I have 30 machines all giving similar errors.  Unable to determine an exact cause.  Some when new window opens, others when resizing windows.  Haven't been able to consistently reproduce.
