POP_OS: Stam VAC Anti-cheat prevents me from playing DOTA2

I migrated almost everything on Linux and, low and behold, the only game giving me issues is DOTA2.

I'm using Steam flatpack, it runs, I can play against bots, I can spectate games. The moment i try to play in matchmaking a VAC messadge pops up preventing me from starting a game.

I tried reinstalling, veryfying the files, installing on a differend hard drive, scanning the disks for errors.

Nothing worked. Any idea?

Edit: thanks guys, it was actually Proton!

You must use the Linux build to play Dota Don't force the use of proton for it or vac will not work

Could it be that you're forcing Dota2 to run with proton? (Properties -> compatibility -> uncheck the box) Because Dota2 runs natively on Linux and VAC marks games running via proton as unverified.

I had no idea, I had some issues running native and I somewhat gaslight myself into thinking Valve somehow deprioritized Linux support.

I guess my problem is solved then. Thanks!

Do you use the native version or do you use proton? I heard that this issue also occures when playing TF2 using proton.

Flatpak? I imagine that's the problem...

Flatpak usually works fine with anti cheat. More likely a proton issue like other people are saying

Indeed, that seems more likely.
