So basically everything seems to work fine, except I have some artifacts on connected external monitors. On my main monitor everything is fine.

Can someone point me out how to improve it? Maybe upgrade/downgrade amdgpu or modesettings drivers, use different kernel version or something?
I recently migrated to a new laptop with the integrated AMD graphics and put MXLinux on it. Before I had MSI laptop with Nvidia+Intel integrated graphics. I mostly used the Intel card and there on Ubuntu 22.04 everything was working flawlessly with my oldish DisplayLink docking station - no artifacts, good performance.
Now this situation makes me regret I've bought AMD computer and not the Intel one :(
I can also try to install Ubuntu based distro to see if that has any difference, but I would like to avoid it as it will take some time to migrate.
