Crashing somewhere in the Intel GPU drivers. Not sure there's anything we can do here. :/

Comment 2 Christoph Feck 2020-02-13 16:53:06 UTC

If this is reproducible, please install the missing debug symbols and report this issue directly to Intel DRI developers via https://gitlab.freedesktop.org/drm/intel/issues

Comment 3 Christoph Feck 2020-02-13 17:09:30 UTC

Sorry, wrong bug report URL. The Intel DRI driver is part of Mesa, so the report URL is https://www.mesa3d.org/bugs.html
