You can note your issue below here

I have recently switched to Kubuntu and have setup Steam with Proton 5.13-2 and installed the Nvidia proprietary drivers.

When i go play a game no matter which one it is (example: it happens in GTA5 and Killing Floor) sometimes when i press and hold the "W" key (or any other movement key) the character randomly stops or starts having very Jittery movement almost as if the input is being registered only every other frame.

Also sometimes the mouse position will change in a sudden burst to a random direction ( like when playing Killing Floor i will suddenly aim to the sky when trying to aim at the enemies), it doesn't happen all that often but it does happen from time to time.

The frame rate doesn't drop and everything that is not movement related works fine. I checked the keyboard settings and it doesn't seem that any setting is what causes the problem. It's sad because i was so excited with how well everything else was working without requiring much effort.

Anyone has an idea of what may be causing this and what i can do to fix this? Haven't found anyone with the same problem on the internet when searching.

Thanks in advance!


Note any particular steps to reproduce it below here

I don't know what one would do to reproduce this, i have just done a normal install of Kubuntu20.04, installed the drivers i thought i should install and booted up Steam to play my games with Proton. It really is a strange problem i don't see anyone else having and i don't know of anything i have done that may have caused it.
