Since a few weeks my Unity games are not working anymore on Steam (not flatpak) on Linux Mint.
I have tried Stick It to the Stickman, Olija and Dystopika. They all behave the same, with the audio starting playing fine, but still on a black screen. After that, nothing happens and even trying to switch window doesn’t work or is extremely slow, requiring a few minutes to have anything happening.
Adding the same games to another launcher (Heroic), makes them work a bit, but eventually they stop at some loading screen and remain there forever.
I am on the latest OS version, I have the latest proprietary drivers from Nvidia, I have tried switching Proton versions and my GOG Unity games all work fine on Heroic.
I don’t know if there are any logs I can submit, but I am all ears for any suggestions.
UPDATE: Solved! The problem was with the fractional scaling feature in Cinnamon. Once disabled, everything went back to work perfectly.
you can exit steam entirely, launch steam from a terminal with the ‘steam’ command, then try to launch the game, tab out, and see what errors pop up in that terminal’s live feed of steam’s logs.
you can do the same with heroic, prolly. don’t think i remember ever having to, tho.
I did that. The games started in the same problematic way, but no logs appeared in the terminal. I also tried with /Dialog after the app ID.
