GPU HANG: ecode 7:1:dfb71fff, in Xwayland

While using Firefox.

I'm on Fedora 33, the kernel was updated yesterday and I started experiencing graphics issues, e.g. black rectangles flashing in Firefox, video playback glitches. Haven't seen these issues before kernel update.

The GPU HANG has happened once, don't know if it's reproducible.

System info:
Fedora 33
Kernel 5.10.9-201.fc33.x86_64
Desktop computer with Gigabyte Z77-DS3H motherboard
Intel Core i7-3770 CPU
HDMI connector used
