Affects Xubuntu 22.04 (Fresh Install) too on Lenovo Ideapad 330s (Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz)

After about 11 days of using 22.04 release, it lead to major loss of productivity due to the flickering. Got headaches. This should have been a release blocker.

I was curious if it affected Debian Unstable on their latest kernel (Linux 5.17.0-1-amd64 #1 SMP PREEMPT Debian 5.17.3-1 (2022-04-18) x86_64 GNU/Linux) and installed it. No flickering on Debian. Seems like it is a Ubuntu only bug.

Below is a list of attempts I tried to fix flicker that DID NOT work during the 11 days of using Xubuntu 22.04:

* GRUB Param `i915.enable_psr=0` workaround https://wiki.archlinux.org/title/intel_graphics#Screen_flickering
* `intel_idle.max_cstate=4` option to grub param https://gitlab.freedesktop.org/drm/intel/-/issues/5569
* Use latest kernel from ubuntu team (linux-oem-22.04)
* Use different kernel with `mainline` app - https://github.com/bkw777/mainline
```
* 5.17.5 - Did not fix.
* 5.16.20 - Did not fix.
* 5.15.36 - Did not fix.
```
* remove package `xserver-xorg-video-intel` https://en.itsmeit.net/how-to-fix-google-chrome-screen-flickering-on-ubuntu.html
