Although upon first glance, the cursors look perfect, in recordings they appear quite wide - maybe 1.5 times as wide.

Cursors aren’t commonly visible on screen snapshots coming from Windows APIs, so screen recording software is usually drawing them on its own, possibly with some implementation caveats.

Can’t suggest much beyond trying standard sizes for the sprite (square, 32/48/64/128/256).

The problem was fixed by changing the sprite's canvas to a square. Thank you for the quick response!
