Steps to Reproduce

  1. Shift + Tab during a game whith mouse bouton and/or movement key pressed
  2. Shift + Tab again to go back in the game
  3. Every command sent before the Shift + tab are still being executed
  4. Press the keys pressed before the Shift + Tab to cancel their infinite loop.

Explanation

I'm currently playing on Ubuntu 26.04 with proton 11 via steam.

When I accidentally did shift + tab I had the steam menu pop up but when I went back in the game, my mouse was lock in the middle of the screen with only a little marge to move and always being attracted by the center of the screen.

I tried doing alt tab to check if the focus was on the game and not another tab but changed nothing, tried to shift tab again and nothing changed.

I didn't achieve to reproduce the bug, but when I was trying to reproduce it in practice range I figured out that when we shift + tab we don't have access to the cursor on the steam overlay + the keys pressed when we shift + tab are still pressed during and after the steam overlay, and we need to press them again to cancel this. I'm gonna detail this bug.
