Buggy & slow

Some of the effects are okay, but it seems buggy and slow. Im using a 13" MacBook Pro with 8 GB RAM. Some of the effects take a long time to render, and the effect-picker seems to get confused about where its at. When I closed my laptop and re-opened it later, the original photo had disappeared and there was no way to refresh the display.
