Ashley regarded this as a non-issue at the issues page.
Well, from the link you'll be able to get the file and a gif showing how a sprite has trouble following the mouse position.
If anyone could try it out, does it also behave this poorly on your machine as well? Is there a fix for it you can think of? it seems illogical for me that for whatever reason I'm unable to follow the mouse with precision. I mean, what games do you ever see it happening?
