Issue: In games like Spider-Man Remastered and Ghost of Tsushima, my SteamOS PC hard crashes and completely restarts itself. Users have reported this same issue on ProtonDB on Spider-Man Miles Morales and Ghost of Tsushima's pages; reporting that the issues stem from MESA 25.3.0. This is the version currently on SteamOS 3.9. This issue does not happen at all on SteamOS 3.7.19. It was fixed in MESA 25.3.3, please update. 🙏

Steps for reproducing this issue:

1. Launch Ghost of Tsushima on SteamOS.
2. Attempt to play for longer than 10 minutes.
