Here it is! I've found the bug about memory leak: the TransparentSpriteColor() is 100000x bugged!
If you specify a sprite ID, it will grow and grow the memory of the app until infinite

You have to use fix a default color for all your sprite or use Spite3D blending mode (awfulll) TransparentSpriteColor(#PB_Default,RGB(255,255,255))
I've join a first test, is there someone here to try it?

Now I have to convert OSME to OSX...
