Not functional, just a glitch... TheLogFather (DadOfMrLog) pointed me towards topics about this and explained it, apparently it's a bug with PepperFlash in Chrome. Thanks!
Hold in an arrow key; it lags. I found this in my Misdirection project and attempted to isolate it, now showing the list doesn't fix it either (as you can see). .game.render: :render.d is important here. It shows how long the program thinks it should wait in order for it to hit the "one frame every 0.033 seconds" mark, and it isn't affected by the lag, so the lag isn't part of the program, unless it's in my simple list replacement script which doesn't actually have any loops in it (I highly doubt it)...though that wouldn't explain the weird framerate behavior.
