It is the GUI protocol like divx etc. either messing up and switching or just being the wrong one, period. On an emulator I know how to fix it, but not a tablet. The cause of it might be an overloaded graphics processor, in which case go to settings in the game, and set fps to 30 rather than 60. If that works, then turning off background apps, and cleaning up space debris, will also improve matters notably. If it doesn't, it's the protocol, and I can't fix that.
