Comment 41 for bug 1878670

Okay, pretty sure have found the right upstream bug, and have what looks like a good workaround.

$ gsettings set org.gnome.settings-daemon.plugins.xsettings antialiasing 'grayscale'

https://gitlab.freedesktop.org/mesa/mesa/issues/2183

The steps to reproduce does kill the session with a gpu hang on the text drawing benchmark, after changing the antialiasing font mode and logging in again, it completes. Will run for the next few days and see if daily crashes continue or not.
