Sorry, I don't feel safe uploading the whole console log, but here's the bit that appears in the console when I click on Steam > Millennium, hope that's sufficient. ```...

Okay, my bad, here's the whole thing. [steamloopback.host-1756266196396.log](https://github.com/user-attachments/files/22000646/steamloopback.host-1756266196396.log)

The issue could be replicated pretty reliably on my LCDeck, but now I'm on OLEDeck, with the game running at 90 fps, and it doesn't seem to happen anymore.

Felt like trying Proton 10.0 Beta, hoping that the fix mentioned above already landed there, but neither Stable not RC branches seem to have it yet.

That indeed has fixed the issue, thanks for the heads up!  Though the resolutions remain pixelated until I restart the game, but maybe that's how the game also works...

Yes, that's why the SteamDeck environment variable override works. Curious why they only enabled it for Deck specifically, similar to the offline functionality in THPS12, btw.
