  • I know this issue. It’s reproducible when

    • Using AMD on Wayland
    • Only on certain screens or only on HDMI (I never reproduced that when using DP)
    • The game is running in non-native resolution, meaning the compositor is doing upscaling
    • The game window is full screen and focused - the black blocks go away if you show some desktop menu or focus other window on top - so basically looks like only happens when the direct scanout protocol is doing its thing
    • not only in Steam games, in most games in general

    The problem has long been reported in Mesa project, but nothing was done to help. My bet is that the bug sits in amdgpu kernel driver and not user space.

    https://gitlab.freedesktop.org/mesa/mesa/-/issues/8705

    EDIT: maybe it’s worth to report in kernel bugzilla or wherever amdgpu kernel driver bugs would go. I don’t reproduce this on my end anymore, because I changed my screen and it uses DP

    EDIT2: I could only reproduce it on RDNA2 and yours is RDNA3. I had Polaris (RX 570) for quite some time and it was running on Wayland. Maybe it only happens on newer cards, maybe it’s regression added along the way




  • I tried all of them and none can handle adding custom kernel modules properly. The longest I spent was on Bazzite, because I could build my custom rpm for akmods, but then it has issues sometimes that the image was built with newer kernel than available and it fails due to being unable to install kernel modules. Long story short it requires full image build. The viable solution would be to ask devs to include the driver I need in their akmods collection, but that’s some random github fork of old driver removed from mainline kernel long time ago. I’d much rather have ability to add that myself.

    I tried Nobara and used its gamescope-session package. It’s just as complete as Bazzite and the final touches are far easier to get. It’s still traditional Fedora, but gaming and HTPC ready almost out of the box.
