glibc, or the GNU C Library, has recently been updated to 2.36. While this release does contain quite a few bug fixes, it’s also created others. For gamers in particular, it appears that this update has caused a regression with games that use Easy Anti-Cheat (EAC). That means MultiVersus, Elden Ring, Apex Legends, and any other game that uses EAC (depending on the version being used) will no longer work on Deck or on Linux via Proton.

If you’re on Arch, please be careful when upgrading your system packages. Avoid upgrading glibc if you can, at least for the time being. If you already have 2.36, there are instructions provided in the GitHub thread to downgrade the package. Fortunately Fedora hasn’t picked up this update yet, and it seems like GloriousEggroll is enjoying himself seeing Arch users suffer. Hopefully someone can figure out what is causing the regression.
