Following up on this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191/comments/16

Booting with 5.15.0-25-generic and the i915.enable_dc=0 intel_idle.max_cstate=2 configs seems to fix the issue on my hardware.

5.15.0-27-generic won't stop shaking randomly no matter what value I test on intel_idle.max_cstate. It seems to get worse when there are many windows on the screen or something is zoomed in/out. For example, on shopping sites like aliexpress, hovering with the mouse on the product normally spawns this window with the zoomed product, I noticed that this caused a lot of shaking. Reading stuff, especially with images seems to cause it more regularly as well. However, watching videos was fine all the time.

I can also confirm that the kernel 5.13.0-20-generic works without an issue with the same hardware as some of my work colleagues have the same machine running Ubuntu 21.10 with that kernel.
