EEVEE Filter Size setting set to 0.00px no longer results in a pixelated viewport, but still outputs a pixelated render #130669

System Information
Operating system: Windows-10-10.0.26100-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 566.14 Opengl Backend

Blender Version
Broken: version: 4.3.0, branch: blender-v4.3-release, commit date: 2024-11-19 08:52, hash: 2b18cad88b13
Worked: 4.2

Short description of error
Prior to 4.3, in EEVEE setting the filter size under 'Film' in the render tab to 0.00px would result in a pixelated view-port, which was incredibly useful for making low res art such as pixel art. In 4.3 the view-port becomes blurry when setting the filter size to 0.00px, but rendering the image still results in a pixelated image.

Attached is an example of what I see in the view-port vs when I render.

Exact steps for others to reproduce the error

In render tab:

Performance > Viewport, Set pixel size to 2x or 4x
Under Film, set filter size to 0.00px. (It has to be 0.0px to reproduce the issue. 0.01px does not reproduce the issue)

In output tab:

Set the render resolution to something low like 720p

Render image and compare the pixelated render to blurry view-port.
Prior versions of blender did not have a blurry view-port.

I can confirm the change in Blender 4.3

I think I know change caused it. But I will bisect it to find out.

The change came from c72a1d698e

Arguably the large blocky pixels in the viewport in 4.2 wasn't correct. So that's been fixed. However I would class the blurry pixels in the viewport as a bug.

I fixed the blurring issue.

Correct, it wasn't correct.

Prior to 4.3, in EEVEE setting the filter size under 'Film' in the render tab to 0.00px would result in a pixelated view-port, which was incredibly useful for making low res art such as pixel art.

Note that while it might have been useful this is not the goal of this feature as it will try to always resolve to the viewport native size.

A proper way would be to use the realtime compositor to resample the viewport using pixelated UV.
