Screen flickering on integrated AMD Radeon GPU

So, I have a laptop and on every linux there is problem about screen always flickering but on some version of the linux kernel, i have no problem (like with the popOS 21.10 kernel). Do you have any clue for stoping screen flickering on thoriumOS for the AMD iGPU users (I hope I'am not the only one with this issue).

I know for sure it's entirely the fault of the kernel or his driver

Thank you (if you need some info or you just can't fix this issue please tell me)

Begin by reproducing the screen flicker on ThoriumOS with the integrated AMD Radeon GPU, then compare its kernel and driver behavior with the PopOS 21.10 kernel, which the report says does not flicker. Done means identifying a reproducible kernel or driver difference and confirming a fix or documented workaround.
