ThoriumOS 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)

@kilam8900 I am using the ChromeOS Flex Kernel + Vanilla Mesa and linux firmware from upstream gentoo. What CPU/IGPU do you have. Can you see if ChromeOS Flex 114 also has the issue. You can get it here https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_15437.63.0_reven_recovery_stable-channel_mp-v2.bin.zip

I tried chromeOS Flex, it's worse because it has the same issue plus my wifi can't work (RLT8821CE). Ill try to get the popOS 20.10 kernel if you need some infos on it and why it dont have the issue.

Also its flickering even more on the wifi registration (I think bcs of the gray background) also exiting sleep mode

After a few tests, I know that the 5.16 kernel work fine, so do you know if i cant update the kernel from ThoriumOS?
