Shaking/wiggling/flickering screen problem with Intel Graphics and also black screen after pluging external monitor
Hi,
I am currently using fedora 34 kernel 5.13.10-200.fc34.x86_64 and I am struggling with the shaking screen issue. The issue in fact appeared from a very start in the system installation menu (it was on July, I do not remember which exact kernel version it was). In that time I also considered installation of Ubuntu 21.04 and when I checked Ubuntu installer I had identical problem.
I figured out that issue disappears after I change screen resolution (next I can go back to my full screen resolution (2160 * 1440 (3:2)) without having this issue till I restart my computer again and problem comes back). When I was using windows 10 I did not observe this shaking screen issue.
Also when I try connect my laptop to external monitor using USB-C/VGA adapter, laptop and external display go gray and I have to hard reset to restore visual responsiveness (system is still working, I can hear sound of music). When I connect external monitor before running laptop both monitor works (internal monitor with shaking screen but at least is't constantly gray), but as soon I disconnect external monitor, the internal monitor goes gray again.
I am using Chuwi GemiBook with Intel Corporation GeminiLake [UHD Graphics 600].
Here's a link to the video of what it looks like in my case:

UPDATE:
Currently using archlinux with kernel 5.16.9-zen1-1-zen with mesa 21.3.6 and problem with external screen has gone. Shaking screen issue still maintaining
SOLUTION!:
Adding Intel_idle.max_cstate=2 to Kernel parameter fix the issue with shaking screen
