UWP - XBOX Series S 4K - Unity UI - very grainy

Hi,

I'm encountering a very strange UI behavior with my XBOX Series S build: the result is, even the console runs in 4K with a 4K screen attached, very very grainy (it does not matter if I switch to 1080p instead).
Even more strange is that the SAME build on the SAME screen - just running as a Windows 10 UWP build - looks absolutely fine. The texture atlas used is uncompressed and all images have a high resolution (512x512). I'm using Unity 2020.2.3f1.

I really have no idea. At first I thought I did something wrong with the texture atlas compression, but as written the same project, just running under Windows, look fine.

It looks like this:



I really have no idea.

Thanks!

To answer my own question - after triggering

Code (CSharp):

1. Screen.SetResolution(Screen.resolutions[Screen.resolutions.Length - 1].width, Screen.resolutions[Screen.resolutions.Length - 1].height, true, 30);

everything looks fine. I thought Unity switches to the highest resolution available by default automatically. It does not seem so.

 

Nope.
