I have experienced this crash on both x11 and wayland.  I have 2 separate crash reports from Dr. Konqi, which I will mark as duplicates of this bug.

This is a crash in the i965 DRI video driver. If this is reproducible, please install debug symbols for i965_dri.so, and report this issue directly to Mesa developers via https://www.mesa3d.org/bugs.html
Comment 5 Benjamin Smith 2019-12-19 20:54:09 UTC 
I haven't experienced this bug recently. Maybe it's been fixed in Mesa 19.3.
