Please check out this video and let me know if anyone can make sense of it or reproduce it. Thanks!

Figured out it's a Dell display thing. This display anyway: P3221D

EDIT: I was wrong. It is NOT specific to just the Dell 32". It occurs on all four 32" 2560x1440 monitors I have tried.

So the file is not affected? It is just a display artifact?

File is not affected.

I spoke too soon. It is a macOS problem and not displays specifically. I have tried 3 different 32" displays now and they all do it.

Make it 4 different 32" displays. Definitely an issue with the Preview app. Weird...

Tried to reproduce this but couldn't.

11.4, Mac Mini 2018, Dell 27" 4k display (HDMI) @3840 × 2160 x 60Hz.
Also tried at 2560x1440 (scaled) to see if it was specific to that res.

No luck. Hmm.

New M1 Mac Mini arriving tomorrow, so I will re-check.

Won't occur on a 27" display at all. I tried 3 of those. It only occurs on 32" displays. No idea why, but it is the case. I wish other people with 32" 2560x1440 monitors would chime in.

I was wrong yet AGAIN! It does occur on 27" displays that are native 2560x1440. I don't know what to make of this now...?
