According to my logs, in the past few days these versions have worked fine:

5.10.0-1045.47-oem
5.11.0-37.41~20.04.2-generic

[Launchpad Janitor (janitor)]

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

[Yury (zyrikby)]

Exactly the same image, however before the login screen after a reboot.
Both available version of the kernel are affected: 5.13.0-23 and 5.13.0-25.
Works fine with 5.11.0-46

Problem can be reproduced with 5.13.0-28.31~20.04.1 as well.

Problem reproduced with 5.13.0-30-generic (20.04.3 LTS)

Seems like it is fixed in kernel 5.14: https://gitlab.freedesktop.org/drm/amd/-/issues/1783

Any chance to get the fix backported to 20.04?

[Yegor Panov (maxpayne1986)]

This is a tricky bug, it comes back sometimes from version to version. Will be great fix it in the 20.04.4 LTS

[Sebastian Nohn (sebastian-nohn)]

Seems fixed in linux-image-5.13.0-39-generic 5.13.0-39.44~20.04.1

[Yegor Panov (maxpayne1986)]

Good. I just install kernel 5.14.21 one month ago and all works fine for me
