As a heads up, the latest update to the lib32-libdrm package (2.4.126-1) from October 19th seems to cause some older games running through proton to either crash on startup or just not start at all after hitting play on steam. Downgrading lib32-libdrm to version 2.4.125-1 fixes the issue and lets the games launch again. Logs for both games I have personally identified as affected mention stack smashing, and can be provided if needed, and I can’t get this reported on the Arch gitlab because no one can make new accounts.
Games affected:
- Fire Pro Wrestling World (personally identified)
- Guilty Gear XX Accent Core Plus R (personally identified)
- Ultra Street Fighter IV (identified by reddit post on the issue)
- King of Fighters XII (identified by same reddit post)
- Plutonium Project (identified by reddit reply)
