So this happens whenever zoom is not 100% (50%, 150% etc).
Probably even with "fit to window" except there are no sliders there.
It's probably because the function that calculates the position of 
sliders should be just multiplied at some point by the zoom ratio - 
currently it 1 and that's why it works fine at 100%....
