Details

troy@netscape.com (using quantify) reported that on a large (6 1/2mb) document we are making many calls to invalidate rectangles which are not visible, consuming 13% of the total load time. As an optimization we should prevent the nsIWidget's InvalidateRect from being performed when the rectangle is not visible.

Target Milestone: M16
Fixed in 3/14/2000 5:38pm build. In quantify, I verified that the code to check visibility of the rect to invalidate takes far less time than calls to invalidate (400usec vs. 24000usec.)
