Quoting Sangeki from the Special K thread:

With anything newer than Proton 9.0-2 Special K causes RAM to fill up to exhaustion on launch of a game. 9.0-3 was recently promoted from RC and is probably causing this issue and your Deck to freeze

Can confirm Special K DLL injection was working before that update.

Hello @SaltyBet, please add PROTON_LOG=1 %command% to a couple game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please explicitly note what OS release you're using as "stable channel" doesn't age well (SteamOS 3.5.19 expected).

OS:
Arch Linux

Proton Version(s):
Working: 8.0-5
Broken: 9.0-3
Last known working version: 9.0-2

Games Tested:
NieR:Automata (524220)
NieR Replicant ver.1.22474487139... (1113560)

Observed Behavior:
Proton 9.0-3: Games launch but run very slowly and immediately start consuming all available RAM and SWAP.
Proton 8.0-5: Games launch and appear to function normally.

This isn't on Steam Deck/SteamOS but the issue isn't directly related to either and the outcome is the same.

it seems like something happened between valve exp and bleeding edge. when i used exp proton tkg/wine tkg it worked fine, but anything newer than that causes games to crash on a fresh Vanilla Arch install.

MMapleHinata 2024-10-19 github

The reason why this breaks is caused by the addition of the (incomplete?) implementation of IAudioSessionEnumerator
Inside Special K, we attempt to enumerate all of the Audio Sessions in order to provide audio mixing in-game, however, Wine memory leaks every time we construct the SessionEnumerator, which we do repeatedly until we get the audio session for the current process, the code responsible for that can be found here: https://github.com/SpecialKO/SpecialK/blob/e727014e2b77d38469b6090ba1d8656c8093d9ee/src/sound.cpp#L486
On the meanwhile, the latest Special K nightly has a workaround for this issue, which from my testing seems to be all that is required to get Special K working under Proton again.

I can confirm that it does indeed work again, starting with Special K 24.10.19. Awesome!

Thanks @MapleHinata / @Sangeki.

Confirmed fixed here too.

Will close the issue.

Cheers.
