Edited:
I reverse part of this as 720p textures does show 16:9 over my entire 1080p monitor i noticed now, but the 21:9 does not.
WSF pre 2026 does not have these behavior, and i could even use any 21:9 frontened textures in diffrent resolutions and it would still fill out my monitor, but now they being rendered in 4:3 with black borders.
Im not sure why this has changed, but thought of reporting it incase its a bug.

and in VC, the splash screens is also original 16:9

We need that fullscreen for backround setting in VC too, because even tho the backround is partially hidden behind the UI, the ammount of "corners" in the new WSF is too many while using custom textures
