I use Manjaro from architect, used an unconfigured KDE with only the plasma-shell, however, I did notice this problem as well on my previous XFCE install.
There is horizontal flickering, most prominent whenever I have a steam game open. I don’t think this is unique to steam or steam games. I have a demo, but not allowed to post links.
I have an intel i5 4590 and an AMD RX570 4GB, with 8GB RAM.
dmesg doesn’t seem to have anything related to mesa or amdgpu
I have tested the following kernels:
5.8 and 5.4 the problem is very prominent, and 4.14 the problem is greatly reduced, but more apparent once I open a steam game.
It is most noticeable on dark colours and gradients.
I noticed this started happening when I moved from preconfigured desktop environments in Architect to unconfigured, though it’s possible there is some other change that coincidentally occurred at the same time.
I also noticed that if I open a terminal window, for example, and move the mouse from the flickering window to the terminal, the flickering reduces or even stops completely, and returns when the mouse hovers back over the flickering window.
When I have something like a steam game open, the flickering is intense, and visible on a static image desktop.
