This bug affects me too.
Ubuntu 20.04 with Gnome. The bug appears when using Firefox in my case.
Downgrading the kernel to 5.4 series solves the issue. I have to downgrade from
5.11, the last version of the Hardware Enablement Stack. The bug is present on
5.11 and 5.8 versions.
Intel(R)
Same here. Still not fixed in 5.8.0-63.
Package installed:
linux-generic-hwe-20.04/focal-updates,focal-security,now 5.8.0.63.71~20.04.45

Downgrade to 5.8.0-43-generic fixes the issue.
