I absolutely don't know why, but my character started to lag when changing scenes. It happens not with all scenes but always with the same scenes. And the weirdest part, where it happens, the scenes are short and not the most heaviest regarding elements, actions or animations in the game. It lags exactly at the position where the transparent character is placed in a new scene and just for half a second. Did someone experience something similar and could fix it? Update: First I thought it had to do with the y-position of the character but I move it around and nothing changed. Now I think it has to do with the jump animation: the characters jump animation is all over my 3 atlasses. Is there a way to get them all together in the first atlass? Even though thinking about it a little more, no reason why it should happen just with certain scenes.
