I'm using DayPilot version 2020.1.3734.1, and am seeing an odd behavior.
We have a page with multiple day view calendars on the screen. When the mouse is used to hover over one calendar, that calendar properly shows an grey overlay. If the mouse is quickly moved to the next calendar, the grey overlay stays on the previous calendar and also on the now hovered calendar. If the mouse is moved slowly, the proper behavior displays where the originally hovered calendar overlay disappears and the now hovered calendar shows the overlay. Any thoughts?
