Update 11/06 - Proton 5.0-9 released with these fixes:

- Fix crash in Final Fantasy XII: The Zodiac Age.
After a public testing period of only a few days, Valve has already pushed out Steam Play Proton 5.0-8 pulling in plenty of upgrades and fixes for the compatibility layer.
The first Release Candidate was put out on June 3 and after what seems like only a few tweaks, like removing the wine-mono upgrade that caused issues, it should now be available to everyone. You should see an update to Proton 5.0 in your Steam client.
From the official changelog, here's the major additions and updates:
- Dramatically improve loading times for Streets of Rage 4.
- Performance improvements for DOOM Eternal, Detroit: Become Human, and We Happy Few.
- Support latest Steam SDKs, which fixes games such as Scrap Mechanic, and Mod and Play.
- Update DXVK to v1.7, FAudio to 20.06 and pulls in latest vkd3d
- On KDE, games being fullscreen should no longer prevent alt-tabbing out of the game.
- Improve gstreamer performance.
As for bug fixes:
- Fix crashes in Detroit: Become Human, Planet Zoo, Jurassic World: Evolution, Unity of Command II, and Splinter Cell Blacklist.
- Fix some Rockstar Launcher errors on some systems.
- Fix crash on launch in STEINS;GATE 0.
- Fix missing network ping times in some multiplayer games like Path of Exile and Wolcen.
- Fix external links in Lords Mobile.
- Fix crash on launch in TOXIKK.
- Fix WRC 7 crash when using a steering wheel controller. Note that some force-feedback effects may require a kernel >= 5.7.
We don't know when Valve plan to have Wine updated for Proton, might be a while since the past few versions have seen some major regressions for gaming.
