Explanation

Mouse cursor randomly jumps to another screen position.

The issue most commonly occurs when performing actions such as:

• Zooming / aiming down sights
• Using portals
• Throwing grenades
• Occasionally firing a weapon

It does not always happen. And not during every game.
But often after I have been killed a few times.
Starting a new game seems to fix the issue.

OS: Linux / Steam (Proton 10)

Leaving the game and rejoining seems to solve the issue in some cases.
