It seems if we are creating like 1000+ timetlines in a scrollable window, my Chrome freezes for couple minutes and takes up 25% CPU all the time. When pauses it, I can see that it stops at auto refreshing redraw even I don't resize the window. Are all timelines are trying to draw/update even they are not visible? Wonder if this is a limitation for number of timelines or there is something I can fix this in our side? Thanks!"}}
