on mac: female trainer sprite is very glitchy

[Former user]

In the attached file are some screenshots. when the trainer has its back towards you, the sprite is the most glitchy, as the black outlines are gone and a part of the trainer is cut off. When facing sidewards, the hair turns kinda purple but you can see this at its best when its running; in my screenshot its standing still so you cant really see it that clearly. When its facing towards the screen, theres nothing wrong, but i added a screenshot of that too. I tried this with all the sprites you can choose, the blond, purple and the brown haired but its all the same.
