steam-2310.log

I confirm:

• [yes!!!] that I haven't found an existing compatibility report for this game.
• [yeah!!!!!!] that I have checked whether there are updates for my system available.

Symptoms

on x11, if i launch any kex engine game (we'll be using quake for this example, the log file is also from quake), i see a black screen for less than a second and then it crashes.
on wayland, if i do the same thing then the game launches perfectly fine (although with bottlenecked performance because wayland on mint sucks!!!).
i feel as though the culprit to this is the BADMATCH error that can be found in the attatched log file - if there's a fix for that, then it should fix every kex engine game on my system
PLEASE READ THIS!!!!: nobody i know has been able to replicate this? for some reason? it only happens on my computer, specifically while running mint while using x11

Reproduction

1. be on linux mint (x11)

2. load into steam

3. launch any kex engine game

4. watch in despair as it crashes instantly

5. reload into wayland

6. load into steam

7. launch any kex engine game

8. watch in horror as it runs horribly
