Issue description

Distorted pixel art - mostly visible on character eyes [with "keep-width" the eyes pop like 3 times the size, on simple "keep" they jump between what appears like 1.5 and .5 pixels] when window is resized to full screen. Viewport V and H are 640x360, Mode: Viewport, Aspect: Keep, Scale 1 int. Did not happen in Godot3, with pixel snap enabled. Both pixel snap options in Godot4 fail to fix it, AND add heavy jitter when moving diagonally. Clean project, with a tilemap, a sprite with animation frames and godot logo. Tried every option in project settings I could find.

Aspect: Keep / Keep height:

Aspect: Keep Width:

It looks like the scale would not stay at a full integer, and instead go into an f, or might be a problem on my end - please advise.

Steps to reproduce

Change the window size / maximize the minimal reproduction project

This is due to uneven pixel scaling. The pixel snap project settings are not expected to fix this.
