UI Unresponsive
Submitted
When running Space Engineers 2 VS2 on Linux using Steam Proton, the game itself runs smoothly and performs well in 3D gameplay.
However, the UI becomes extremely unresponsive, and the mouse cursor does often not align with clickable UI elements.
When opening any inventory or options menu:
- Buttons highlight only after a long delay (500–1500 ms) and me wiggeling my mouse
- The game acts as if the mouse is not where it visually appears
- Selecting items requires slowly hovering until the UI “catches up”
- The rest of the game (movement, rendering, FPS) is normal — only UI is affected
This makes inventory management almost unusable.
I attached a video showing the behavior.
