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.
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.
