Flatpak graphics errors on Bazzite KDE Wayland (AMD R9 270X 4GB)

Hello everyone,

I hope I’m posting in the right area of the forum and full apologies if I am not.

I’m running Bazzite with the KDE Plasma desktop environment on Wayland and I’m encountering some issues that I could use some help diagnosing.

My system has the following relevant hardware:

Graphics Card: Sapphire Radeon R9 270X 4GB GDDR5
Kernel Driver in use: amdgpu (confirmed via lspci)

I am reasonably new to using Linux, so I have been trying to work through the issues with Google Gemini and eventually it has recommended that I post to a Bazzite forum to seek further help. (Cards on the table, it has also helped me with writing up this post too)

My main problem is steam is failing to launch any game at all, no matter what version of proton I use…

with the help of Google Gemini:

I’ve been looking at the system logs (journalctl -xe) and have noticed some errors.

I recently performed a full system update using rpm-ostree upgrade and also ran flatpak update (which reported “Nothing to do”, indicating my Flatpaks are up-to-date according to the repositories). I also rebooted after the rpm-ostree upgrade.

  • Before the update: I was seeing frequent KDE startup errors related to kwin_wayland (OpenGL GL_INVALID_OPERATION), KSplash failing, and plasma_waitforname timeouts.
  • After the update: These specific KDE startup errors seem to be gone from the logs, which is great!

However, I am now seeing graphics-related errors from flatpak processes in my logs. For example:

May 03 16:04:28 bazzite flatpak[4514]: [56:56:0503/160428.993214:ERROR:ui/gl/gl_surface_presentation_helper.cc> May 03 16:04:35 bazzite flatpak[4514]: [56:56:0503/160435.096194:ERROR:ui/gl/gl_surface_presentation_helper.cc>

I also noticed another error appearing in the logs when a game session ends, which seems related to game recording or an overlay tool, but I suspect it might be a separate issue from the core game performance problem:

May 03 16:08:37 bazzite steam[3087]: ERROR: ld.so: object '/usr/lib/extest/libextest.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

Since my graphics driver (amdgpu) is loaded correctly and I’ve updated both the base system and Flatpaks, I’m a bit unsure how to proceed with diagnosing the game launching issues and the flatpak graphics errors.

Could anyone offer some guidance on potential causes or further troubleshooting steps for this kind of issue with my hardware (AMD R9 270X 4GB) on Bazzite KDE Wayland?

Any help would be greatly appreciated as I would love to get this OS up and running as it looks great!

Thank you.

This probably comes way too late and I don’t know if it’ll help at all. But GCN1 and GCN2 cards (yours is GCN1 also known as Southern Isles) usually need to be enabled properly via kernel arguments.

You could try:

sudo rpm-ostree kargs --append='radeon.si_support=0 amdgpu.si_support=1'

I would assume Bazzite already sets this if you chose the correct drivers for your downloaded image.
