PayPalValve have pushed out a small update for Proton Experimental for July 25th, bringing a few fixes across a bunch of games.
Proton Experimental is Valve's staging area for the latest fixes and improvements for the Proton compatibility layer. Eventually the changes will make their way into a stable numbered Proton version. Be sure to check out the GamingOnLinux guide for all the different Proton versions.
All that's changed is below:
- Fixed Chinese font rendering in Warage.
- Fixed screen reader not working in Diablo 4 - requires download of Proton Voice Files.
- Fixed Proton Experimental regression that caused Mortal Kombat 11 getting stuck on a black screen.
- Fixed Proton 10 regressions:
- Rockstar Launcher's birthday date selection dropdowns work again.
- Call of Duty: WWII should no longer fail to render properly in fullscreen native resolution on setups with dual monitors.

Just want to add that WWII is no longer safe to play due to a new RCE exploit discovered. It is unclear if it only affected the windows gamepass version or if it was just exposed due to the uptick of players, but for all safety it is best to avoid Call of Duty: WWII Multiplayer or Zombies. Not worth risking your PC.
