POE1 doesn't launch under Wayland (on Arch Linux) anymore

Hello :)

Since a couple of days POE1 does not launch anymore under Wayland. Instead when launching the game via steam, POE does not launch and the steam client crashes after a couple of seconds. It worked perfectly fine for the beginning of keepers all the way to around the fourth week of 3.27. I also think that I might have dabbled with wine a bit and I may have run "wine PathOfExile.exe" in an attempt to run POE without steam. According to the logs below, steam cannot access the Xwayland socket, which should be enabled. When switching to gnome/x11, the game runs perfectly fine but when under wayland it does not anymore. Anyone with similar behavior?

My Specs:
- latest Arch Linux version from 04.01.2026
- AMD X3D CPU and AMD GPU
- Niri, a Wayland desktop manager (XWayland is enabled too, since "echo $DISPLAY" shows ":0" and niri enables xWayland per default)

What I have tried to so far:
- updated arch
- reinstalled both steam and POE1
- deleted wine
- enabled and disabled Steam Overlay in the steam game settings
- double checked that AMD drivers, and steam related libs are present and up to date
- tried to launch with various Proton versions: 9.0, 8.0, Hotfix & Experimental
- tried these launch commands: STEAM_DISABLE_OVERLAY=1, PROTON_ENABLE_WAYLAND=1, PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%,

Steam logs when trying to launch POE1:

Also having issues on Linux:

Moved from Windows 11 to Mint 22 cinnamon 2 days ago Jan 3,2026.

POE-1 installed and ran fine. Good Fps.
Today it will not let me load past a couple seconds into the Grinding Gears Landing Screen.

**EDIT**

Changing Compatibility mode to Proton 10.0-3 did the trick.
