Oh huh - I guess you can’t really have a fractional number of pixels in an image, especially not in WinAPI.
You can more specifically fix this by making your scale a formula like round(width * scale) / width, which for 32px would give you 2.65625 and hit that exact number of pixels.
I’ll handle this slightly more properly in the next version though strange scales will likely look slightly off since cursor “origins” are whole numbers on Windows.
