At larger scale factors, Windows renders the cursor from an SVG source. It's not clear if there would be a compatibility issue with straightening the arrow image at larger scales since it uses a hardcoded .cur image at small sizes.
Additionally, Windows 10/11 go to some extent to hide cursor scaling from applications. Win32 GDI/USER calls only see the base 32x32 arrow cursor and only DXGI Output Duplication (screen capture API) can see the real cursor. This causes other problems, though, such as various bugs and inconsistencies with custom cursor images.
