Short description of error
For some reason my model looks small on eevee next
Exact steps for others to reproduce the error
Just open my .blend file
Or
Render Properties -> Performance -> Viewport -> Pixel Size
to something larger than 1x. You should see the issue.I can confirm this issue. I will look into bisecting it.

Eevee Next: Small modelsto Blender 4.3 Eevee Next: Viewport Pixel sizes other than 1x render improperlyCaused by

When disabling the overscan the image draws correctly. Seems to be an oversight during refactoring. Is also an issue in Blender 4.2.
Seems when pixel size != 1 the overscan is off. The difference is the same for any number so might indicate a missing *2 somewhere.

So putting my attention to the view matrix that is created in this case.
Here the overscan doesn't seem to be adjusted with the pixel scaling but with the cropped viewplane. Will double check with Clement before patching.
