Description
With Proton 5.13+ (and experimental), when using wine virtual desktop, no matter what resolution I set, it seems to be stuck in the bottom right corner, often having the game go 60% off screen etc, or if running windowed, it may even go completely outside the wine window!



The first two images have the virtual desktop at 2560x1440, and the other one at 1280x720, where the "action" goes outside the real area.
FWIW this doesn't happen with Proton-GE 6.1.

Research direction
No files, tests, or entry points are named. Start by reproducing the virtual-desktop behavior with Proton 5.13+ and the fullscreen hack at the reported resolutions, then compare it with Proton-GE 6.1; done means the game remains within the configured virtual desktop and window bounds.
