Lichess bug

My mouse slips very often , so is this a bug?

It happens to me too! It could be a bug, or may be it is the problem with a certain browser (I am using Firefox) or may be even a type of mouse?

Also whether you go back or forward with your keyboard or mouse wheel, sometimes pieces go back to its original position. @thibault
