Hello! I've seen discussion with similar problem, though in last post there Matthias said, that this should be fixed. So i guess this might me little bit different. (here is the short video https://www.youtube.com/watch?v=Cn1jbuwrEWE)
Well, the problem is in the title. Sprite starts to jitter while moving. I was just following GurkNukem tutorial, except for setting KeyboardEntityController as player controller. I've also tried digging into engine source code, but with no luck.
