gnome-shell assert failure: gnome-shell: ../src/gallium/drivers/radeonsi/si_state_viewport.c:239: si_emit_guardband: Assertion `left <= -1 && top <= -1 && right >= 1 && bottom >= 1' failed.

[Tom Reynolds]

When I returned to my computer (AMD RX580 graphics, amdgpu) after a while (the screen had entered power saving mode), the gnome-shell process (on XWayland) failed.

Unfortunately this crash was not automatically reported by whoopsie / apport and required manual re-submission (bug 1792643). If this was also so for the other (to date only) three reporters, this would explain the low number of reports on errors.ubuntu.com.

This is a dupe of bug 1837087 (I'm just filing this here to make some of this more searchable).
