Research direction

The report provides no source file, test, or entry point; start by reproducing SteamOS 3.8.28 on the Strix Point/Radeon 890M system and switching to Desktop Mode. Done means identifying the cause of the green flickering screen and confirming that Desktop Mode displays normally after the fix.

Please describe your issue in as much detail as possible:

I have SteamOS installed on a Bosgame M6 mini PC running 32GB DDR5-5600 & the AI 9 HX 370 / Radeon 890M. It should work ok, but with the last several updates would increasingly have issues switching to desktop mode, showing a green flickering screen instead of the KDE desktop. I have it hooked to a 4K Samsung TV but that shouldn't cause issues?

Steps for reproducing this issue:
  1. Install SteamOS on a Strix Point machine
  2. Switch to Desktop Mode
  3. Should flicker green
