Hi there So my students and I have build an arcade machine, to showcase our productions to the rest of the school. Works great. It has a "hub" from where all games are launched. Also great. But this hub has some UI elements which are animated from the Animator system. Colors, and transforms and such. Those run forever. When the hub has been running for a couple of days, those animations begin to fail. First they'll get slower. And slower. Until finally they are so slow, that they seem to not animate anymore. That happens around day four. Everything else is still very responsive. Inputs to the hub, and general "Update" functions seem to run normally. So it is not the project itself that slows down, only the animation system internally. My own little theory is that each cycle will increment some internal state. And then memory, over time, will get filled with garbage, which the garbage collector fails to clean, due to it not being de-referenced. Something. My fix for now is to destroy, and recreate certain UI elements (Having made them into prefabs that I can load from "Resources"), when they have been running for some time. But it still feels like a hack, that should be unnecessary. Anybody having a clue what's going on, and how to fix it for real? Is it a bug, or is it simply would is to be expected when having a game/project just run for days on end?
