(Automatically) Chosen kernel in these instances is the 5.8 kernel.
NO issues with the 5.4 kernel - or the 5.8.0-48 kernel

Problem: Operating system graphics (eg kubuntu calendar) and firefox (using webrender) have issues (see attached for example)

Status changed to 'Confirmed' because the bug affects multiple users.

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 amd64 [installed]

Downgrade to 5.8.0-43-generic fixes the issue.

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.
