Typically if you see cells flying around like that, its an indication that you've left an old style animation block open (the begin/commitAnimations APIs).

As for the rest, it doesn't make sense that, for example, the arrow renders multiple times over itself unless you are doing something relatively strange with -drawRect:'d drawing, but given what you've described implementing this functionality via -drawRect: would be a lot more work than is necessary.
