Not to be mean, but lack of staff reply for ~1 year, even if that reply would be a "sorry, we're not going to fix this" line, is rather ...disheartening.

are you possibly using a custom cursor? this can cause myriad of issues,even the default pointer with enabled ancillary
pointer behavior (e.g. shadows, trails, non-default pointer shapes, precision
