Original report
Problem
Steam games using Proton crash immediately after launching (2-3 seconds, no window appears). Affects multiple games (EU5, CS2, etc.).
Environment
- Omarchy with Hyprland (Wayland)
- AMD GPU
Root Cause
Proton/Wine games expect X11 window management semantics (fullscreen handling, input grabbing, etc.) that Hyprland/Wayland doesn't provide directly. Games fail to initialize and crash silently.
Solution
1. Install required packages
sudo pacman -S vulkan-radeon lib32-vulkan-radeon lib32-mesa lib32-gnutls lib32-libpulse gamescope2. Add launch option to Steam games
Right-click game → Properties → Launch Options:
gamescope -W 1920 -H 1080 -f -- %command%Adjust resolution to match your monitor.
Why this works
Gamescope creates a nested compositor that:
- Provides a proper XWayland environment games expect
- Handles fullscreen mode translation between X11 and Wayland
- Manages input grabbing correctly
- Acts as a compatibility layer between Proton/Wine and Hyprland
