I have no custom cursor size and my display scaling is at 100% at 1920x1080. This issue was on both of my PCs (A desktop with a single 720p screen and my laptop that I always use that’s 1080p), so it has nothing to do with multiple screens or screen sizing for me.
Here are all the specs that I currently have in my bug report about this:
It only occurs on Direct3D11 for me. I since swapped to Vulcan, which runs faster on my PC as well as also have no issues at all. The only issue I currently have is that Roblox Studio is way laggier than the Roblox Player when it originally had nearly the same framerate with Studio being slightly slower (which that was understandable).
