Public bug reported:
Since I've switched my laptop to use only discrete GPU (using BIOS switch),
I've been experiencing screen flickering and weird behaviour in some apps, like
text being typed slowly, title bars not appearing and even content being shown
blank.
I've tried changing refresh rate back to 60Hz, installing older drivers (515),
installing driver from NVIDIA website, enrolling the driver key into SecureBoot
DB. Upgrading to Ubuntu 23.04 didn't help either.
There is no AMDGPU driver installed
