Symptoms

On Ubuntu 24.04.5 LTS, The Witcher 3: Wild Hunt GOTY / Remastered appears to interpret my German QWERTZ keyboard layout incorrectly. The Z and Y keys are swapped in the game.

The issue occurs with both Proton Experimental and Wineland 11.0-20261005 when launching the GOG version through Heroic Games Launcher.

The Elder Scrolls Online works correctly with GE-Proton Latest on the same Ubuntu installation, without the Z/Y key swap.

I have checked the following:

  • Ubuntu uses the German keyboard layout correctly.
  • The Wine prefix registry contains keyboard layout ID 00000407 (German).
  • The game's keyboard_layouts_description.xml maps ID 00000407 to input_qwertz.
  • The game's input_qwertz.ini contains QWERTZ-specific bindings.
  • The saved input.settings contains entries such as IK_Y=(Action=CameraLock), consistent with the QWERTZ configuration.

The configuration appears correct, but the game still handles the keyboard input incorrectly. The exact cause is not yet known.

Reproduction

  1. Use Ubuntu 24.04.5 LTS with GNOME on Wayland and a German QWERTZ keyboard layout.
  2. Use the installed GOG version of The Witcher 3: Wild Hunt GOTY / Remastered.
  3. Launch the game through Heroic Games Launcher using Proton Experimental.
  4. Check the behavior of the physical Z and Y keys in the game.
  5. Repeat the test with Wineland 11.0-20261005.
  6. Observe that the Z and Y keys are interpreted incorrectly with both runners.

Separate Steam logs have been created for the tests with Proton Experimental and Wineland and can be attached to this report.
