davidbienvenu@: Based on your investigation for bug 829137, is there any action here?

Comment 8 by davidbienvenu@chromium.org, Aug 6 

No, I didn't find any action here - from what I could tell, the window frame is NOT being painted more often by scrolling web content.

Should we just close this as wont fix?

Status: WontFix (was: Assigned)
Yeah, closing per #8. In general this change made the UI correct, so if the magnitude of the regression is low then this is fine.
