Potential bug: QiYi Smart Cube sensor delay

With the QiYi Smart Cube and Google Chrome, often a face is not recognized as turned until I turn any face again. For solving, time keeps running because the virtual cube is not solved (the actual one is) but jumps back to the correct time the cube was actually solved after turning any face again. This occured with two different cubes, so either both sensors are broken or there is a bug.
