Input.Delta and UserInputService:GetMouseDelta() does not work correctly on 4k monitors

[aaron_mccoy (PleaseDontBanAaron)]

Reproduction Steps

(On a 4k monitor) Right click and drag to rotate the camera in only 1 axis (Live mode or in Studio mode).
The Camera will rotate both horizontally and vertically instead of just one of the two

Expected Behavior

The Camera to only rotate in one axis

Actual Behavior

The Camera rotates on both axis. Seems like the delta isn’t being calculated correctly on 4k monitors. I have both a 1k and 4k monitor in my setup, and when I move studio to my 1k monitor, the issue no longer occurs.

Issue Area: Engine
Issue Type: Other

Hi, thanks for your patience! Could you check if this bug still occurs? If it does, could you also share your monitor’s resolution, and if possible, the monitor model? That information would help us debug further. Thanks!

Totally forgot about this old bug report. It’s been long since resolved, you don’t need to be worried about it.
