So, this is actually a debug player issue, not haxeflixel, but I am hoping you guys may know of a solution...
Whenever I build a test or relase flash build and run it in the debug player, there is a very significant slowdown any time I have the mouse over the debug player and I move it. There is about a 50% frame loss whenever the mouse is moved.
Does anyone know how to make that stop? Thanks!
