<#secure method=pgpmime mode=sign> What if I use text-property, is there same problem? Set line-height property.

Maybe then we could propose a workaround. I try to add overlay which is colorized blocks that have line-height based on the org-agenda clocked time. I hope the overlay can keep line-height even I split window get window width decreased. I don't think such a feature exist, sorry. maybe someone else can think of a workaround.
