Image scaling using Bazzites GameMode interface

Long story short, the image is not scaling properly only when using the Bazzites own SteamDeck like interface called "Game Mode".

Steps to reproduce the issue:
  1. Install Sunshine game streaming on BazziteOS.
  2. Install Moonlight on whatever system you want as a client.
  3. Start Moonlight on the client to connect to the BazziteOS.
  4. Start any game, and set the in-game resolution to something lower then your native resolution(ex. 720p)
The result is visible on the attached screenshot.

Notes:
-This issue does not happen when launching a game from desktop instead of GameMode.
-This issue does not happen when launching a game from the original Steams BigPicture instead of GameMode.
-Changing the scaling factor to anything but the default "Linear" resolves the issue, but the FPS is basically cut in half, so that's a no go.
