Ran right out of the box. Played several matches and had no issues.

Some days ago it worked with a Pronto or/and without compatibility.
Proton, GE-Potron, Proton Experimental.
Don´t work, Marvel Snap works with "STEAM with RPM Fusion free for Fedora 38" you can try it with BlendOS.

the game run smoothly without any issues

Tenho uma outra máquina com Ubuntu 22.04 LTS, mas não rodou de nenhuma maneira. No Pop OS rodou na hora, sem nenhuma modificação.

STEAM with RPM Fusion free for Fedora 38
Very Good. BlendOS.

Freezes Computer
I saw a window, then it went fullscreen, the mouse cursor changed to an in-game one. The cursor does not move. Whole computer frozen.

I'm able to install Marvel SNAP via Steam on ChromeOS and it loads fine. However, when you click on the link to login to your Google or Apple account it fails to load a browser to complete authentication.
When clicking on the link for auth you get a gnome "Open With..." dialog saying there are no apps available.
It does work if you don't try to login to your account.

I play the game on my laptop's integrated graphics card. if use Proton Experimental will get degredation performance ( about 40 ~ 60 fps ), but Proton GE works fine (stabilized at 60 fps).
So much lag that I couldn't really play the game.

Works like native
Works perfect. But if you are using Flatpak version of Steam you can't log in to your account use your distro's repo version.

It won't connect to the servers or let me sign in through google
I can't get it to work, i get into the main screen, then it will just keep stuck in the loading screen, if i try to sign in It just won't open a browser, idk if its related to flatpak

Steam (Native via RPM Fusion)
Steam Flatpak refuses to let game open a webpage, which is required to login and start playing. Issue does not occur on Steam Native and runs perfectly there.

Had to force Proton Experimental to start the game.
You need to switch to Proton Experimental to play the game
the game start for about 5/6 seconds than closes
PROTON_USE_WINED3D=1 %command%

Game doesn't start
Can't start the game regardless of the Proton version used (tried 8.0-3, 7.0-6, Experimental, GE-7.55, GE-8.15). Steam starts the game, button switches to "Stop" for a moment and comes back to "Play".

Playable
Runs okay, perfectly playable

Game runs great!
Only issue that i found was that when trying to login in-game with google account with Flatpak Steam wont let me login, but with Steam deb its working
Works like its Native

PROTON_USE_WINED3D11=1 PROTON_NO_ESYNC=1 %command%
it works again, but not as good as it was with the previous version
immense lag and stutter in landscreen mode (new), you have to go to the ingame settings and switch the landscreen mode off, then it will fall back to the old portrait mode
https://www.protondb.com/app/1997040#xKBzrQYbeK this was my previous report. now after the recent update i have updated the required launch parameter and added information which ingame setting must be changed to reduce the lag.
I really enjoyed playing it on desktop, especially in high setting since all cards pop out
gamemoderun %command%

PROTON_USE_WINED3D=1 %command%
sometimes a weired kind of echo
sometimes it freezes, but the game itself got very unstable
only steam native client works (i tested with .deb debian package) the flatpack version has very bad performance and can't log in!
PROTON_USE_WINED3D=1 %command%
Worked Fine
Everything seemed fine. I did not link any accounts, so didn't have any problems there.
It worked excellently for a while, and a recent update (I believe to Snap, not Proton) caused it to begin laboring for performance
Just install and play it. Nothing else to do.
Web browser login
audio seems to be not working for now, otherwise runs perfectly via proton.
Just audio missing.
If someone isn't concerned with account linking it runs great on Steam Deck.
