When switching between elements our Box Model sidebar updates with a pretty significant delay. I noticed delays ranging from half a second to 4-5 seconds. Initially I thought that it isn't updating at all but it seems like it just takes a long time. When you switch from Box Model to any other sidebar tab and then back, it updates immediately. STR: 1. Open medium.com (thats where I can reproduce it consistently) 2. Inspect header 3. Open box model sidebar 4. Switch between elements in the element tree. Then you should notice delays.
I can confirm this is an issue

I think it's a regression of the "Make highlighter remote" bug. I started to get the issue at that time.
We need to make the layout view only update on layout change... we have access to this from an actor. At the moment we are using MozAfterPaint on browser which makes the layout view update way too many times... moving the mouse is moved across the browser will refresh it hundreds of times.
I may have filed a duplicate of this bug at #999712. In my case, when there is a delay in the Box Model diagram being updated, what causes it to finally update is moving the mouse cursor into the Box Model pane.

Yes, this was fixed as part of switching to the reflow actor in bug 997198.
