[SOLVED] Unity games downloaded from Steam not working on Linux Mint (lemmy.world)

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.

try to start steam (or the game) via the konsole and check for error messages.

you should also check protondb and look if you need a specific proton version if you haven't tried them all or add some tweaks in the starting options.

good luck OP i hope i was of some help

I could start the games using steam steam://launch/appid_goes_here/Dialog, getting the same experience, but nothing was printed in the terminal and I cannot find any log files.

Launch the actual Steam client from a terminal is what they mean, not just the game.
