  • Expeditions: A Mudrunner game
  • Steam AppID: 2477340

System Information

  • Steam Deck Oled
  • Proton version: 10

I confirm:

  • [X] that I have checked whether there are updates for my system available.

Symptoms:

During the gameplay on a specific maps (Transylvania Alps) devs created a video glitch effects (like a radio interference in front of the camera) that cause a total black screen on Steam deck only. I tried to run the game on a "standard" windows pc and the glitch effects is rendered without any issue but on my Steam Deck I got a a black screen.

Hello @masterzone3d, for someone not familiar with the game, is this somewhere easily accessible? Can you share a save file with instructions to reproduce the render quirk?

Sure! For reproduce this you need to be at exactly on the place where the glitch effects is on. I can make a save file on that point and instructions (very easy) to see the issue. The game need the year pass 1 (the only one on the shop) or the Transylvanian alps map (dlc).

Could you tell me where are stored save files for that game on the steam deck (or windows)? so I can upload it here
