113011 - toolbar tooltip on page makes scrolling very slow

Status: VERIFIED WORKSFORME

(Core :: Layout, defect)

Description

[Jeremy M. Dolan]

Load a page that's long enough to scroll, like http://mozillazine.org/
Click the page to give it focus.
Hover the mouse over a tab, PT bookmark, or navbar stop/reload/back/etc, so
    that when the tooltip apears, it is at least in part overlaping the
    document area. ("docshell"?)
Hit pagedown to scroll down.

What happens:
  docshell renders as all black for .5 seconds, before drawing new area

What should happen:
  no/negligable differance from scrolling without the tooltip

If you hit pagedown again, it blacks out again, etc. Scrolling up works as well,
if you start at the bottom, and make the tooltip pop up there.

I often trigger this as I load a PT bookmark, and leave my mouse there to scroll
the the kb.

this seems fine to  me in  the  latest windows and linux builds. I'm not seeing
any slowdown.

Now scrolling deletes the tooltip. Fine by me.
