Animate leak?

[pvdz]

I notice that over time, animate becomes slower and laggier. At the same time, the tick callback remains stable. This problem is stronger and appears faster on the ipad. I'm not sure what the problem is, but you can check out my game if you want a real world case.

This will need to be resolved. I hope it's not my own fault... :/

Can you please make a reduced test case?
