Huh? This is only when resizing. And resizing was already painfully slow.
Trust me, the meters are definitely not the problem. They are fast now.
The resizing slowness has been there for a long time.
It's caused by something else. Yeah, I would like to fix it, too.

Nope, full redraw is required. 
Think about it - the whole thing needs to stretch.
When not resizing, and just playing, they do use that technique, now.
