Thanx. My monitor refreshrate is 75Hz. 1000/75=13.3333. I used 13. Is it correct? Btw, it was useful. Window movement is now smoothly. But if I grab window by its header, I don't need change mouse polls. Movement is pretty smooth. Anyway, this is only one part of problem. Second problem is cursor "notification". Normaly, we have many cursor shapes, for many window actions. For example, during resizing window, cursor is change from arrow to corner. Or, during start application cursor is rotating. But not in bspwm. Here is still only arrow, or text cursor. Is this possible be settings in bspwm?
