AMD RX550 Artifacts

Hey everyone!

After installing a new RX550 card I noticed some weird artifacts appearing. Nothing too severe, just some random horizontal stripes, but noticeable nonetheless. The strangest thing is, they don’t appear in games or video or any other apps, only on desktop environment itself. Is it a problem with the graphics card itself, or with the driver, or maybe with the PCI slot (I have an ancient MB with PCI 2.0)

Would really appreciate your help!

Here’s the output:

Interesting, I have a Radeon card, too. Older, the computer was built back in 2014:

  Device-1: AMD Caicos XT [Radeon HD 7470/8470 / R5 235/310 OEM]
    vendor: PC Partner / Sapphire driver: radeon v: kernel arch: TeraScale-2
    bus-ID: 01:00.0 temp: 41.0 C
  Display: x11 server: X.Org v: 21.1.7 driver: X: loaded: radeon

    6.1.12-1-MANJARO LLVM 15.0.7) direct-render: Yes

This works for me with no problems at all. This card is probably not suitable for playing modern games, but since I have zero interest in playing games, this is not a problem for me.

Found this:
Maybe worth a try…? Maybe one of the staff knows if it’ll work. I’m just an amateur. 8)

Thanks for your reply! Unfortunately, these drivers are for Ubuntu, Red Hat and Susie based systems. They got noting for Arch-based systems assuming everything is there already…

First of all, old cards and old mobos need old kernels.
Second, give it a try to opencl-amd package from aur.
