Proton log: NOTE: the web view does not pop up at all when running with PROTON_LOG=1. I can only make it come up when the logging flag is not set.

This game is listed as Deck Verified.

Symptoms

Log into Xbox Network (syncs achievements/etc with Xbox Live) does not work. It will variously lock up the game in gaming mode or open a web view that eventually gets stuck on a blank white screen in desktop mode. When running with PROTON_LOG=1, the web view does not come up at all, which is interesting.

Miscellaneous other issues: I cannot uncheck Full Screen in the settings, and the display resolution dropdown is blank.

Reproduction

1. Launch game in gaming mode
2. Click Log into Xbox Network (Y)
3. Game gets stuck "Logging In..."
4. Force the game to quit with Steam button
5. Switch to desktop mode (attach keyboard and mouse)
6. Launch game
7. Click Log into Xbox Network with mouse
   
8. Use keyboard Super key to get the taskbar focused
9. Minimize game from the right click menu of the taskbar icon
10. Enter credentials for Microsoft account in the web view - NOTE: I needed to use a different Windows PC to approve the app the first time.
11. Web view gets stuck on white screen instead of logging in the game
    

No source file or test is named. Start by reproducing the Xbox Network login flow on Steam Deck with Proton 7.0-5 and inspect the linked Proton log, comparing behavior with and without PROTON_LOG=1. Done means login completes reliably and the reported fullscreen and resolution controls behave correctly.
