When I'm dragging blocks around or moving a page with blocks UI is slow

Hello,

When I’m dragging blocks around or moving a page with blocks UI is slow: blocks are not being redrawn until I release mouse button. Have checked similar services and they feel much more responsive, components redraw instantly when I move blocks or page, or zoom in/out. Tested on FF 69.
