System Information
Operating system: Windows 10
Graphics card: GTX 1060

Blender Version
Broken: 3.0.0
Worked: Only used version above.

Short description of error

Rendering with F12 in Blender and the built in image viewer shows jaggies. Its not in the actual image as looks fine in Windows Photo Viewer. See attached images.

Can clearly see around the clock there's scaling jaggies in Blender, Fractional Zoom is already at 1:1.

ps. Would be nice to have a zoom percentage shown in Blenders image preview too!

Cannot reproduce here (might help to share an example .blend file here -- or does this happen with any image opened in the Image Editor?)
Does this issue change/improve/vanish if you alter the Display Aspect slightly?

Does this work in 2.93?

Then this might be a duplicate of #92903 (Artifacts in image editor)

So I really think this is solved since bdd74e1e93 (at least #92903 is for me).

@Billy-Blair : please try a fresh build from https://builder.blender.org/download/daily/

The 1.00001 on Y axis worked. What also worked was dragging the Render Image window in Blender to be slightly larger and the jaggies went away.

Will check out newest daily build.

3.1.0 Beta seems to have fixed the issue.
