Horizontal Flickering Which worsens under certain conditions

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.

Any ideas?

Please read this:

and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

  1. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
  2. The contents of /usr/share/X11/xorg.conf.d/ with any AMD / Radeon / … specific configuration would help us help you too! :wink:

P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which CPU/GPU you have, …

For anyone who finds this post, I have found out what the error was. This is the same bug as


It is a problem in the automatic power switching, and it is a bug that has persisted for a number of years. If you go to


and find that the default value is auto, you can change to low or high to see if this resolves your issue. I personally use low because I don’t want my gpu running on high power all the time. There are some other solutions revolving around setting the GPU clock and the like, but this is the solution I took.
