My mouse goes crazy sometimes in Minecraft?

I recently started playing the Win 10 Edition of Minecraft. Sometimes when I actually bet something or even do nothing at all, my "character" suddenly starts beating around wildly and breaking things down. Why is that?

If you play on servers it could be people who help your character with the help of programmers (also called plugins) control your character in order to fool you, nothing happens to your PC.

if you play single player, I could explain it to myself that your PC is possibly overloaded and notices things like mouse clicks or keystrokes a little later because it has to process the old ones first.

I once did that with mods because my old graphics card was quite overwhelmed and everything I did only really arrived 5 seconds later

I only play single player. Nevertheless, I'm surprised when I build large areas and actually do not dismantle anything, he starts to dismantle all at once and my PC is a gaming PC, should it actually work.

Well, every PC is different. There are just powerful and those who are rather weak.

I can't explain it to myself otherwise.
