I've implemented an CADisplayLink callback to perform an heavy animation on screen. However, it seems that sometimes a frame is dropped or just not drawn. I'm not sure. Don't have a highspeed camera at hand to record it. But maybe someone knows in depth what happens if my callback is calculating too long?
Will the callback not be called for the next frames until it's done? Or will it be aborted/ignored on every iteration when it's not fast enough?
