Video footage of the cursor bug in Counter Strike 2.

SUMMARY
When opening a menu in a game, the mouse isn't always reset to center, it will
if the camera angle in-game doesn't change and the menu is closed and reopened.
It feels inconsistent and I'm often looking for my cursor on screen.

STEPS TO REPRODUCE
1. Launch a game from Steam (Proton/Native).
2. Open up a menu where the cursor normally would be centered on the screen.
3. Observe current cursor position.
4. Exit the menu.
5. Move mouse around in-game.
6. Open up the menu again.
7. Observe updated cursor position.

OBSERVED RESULT
The cursor changes location when bringing up the menu after moving the camera
angle in-game.

EXPECTED RESULT
The cursor should be centered upon opening the menu after moving the camera
angle in-game.
