Details

When you mouse over a link in current builds, the entire HTML content area repaints (even when nothing changes position). The problem appears to be in some reflow code, which appears to be doing a two- pass reflow. In the first pass, the height of the view is changed (from 5085 to 5092 twips high in one example), and in the second pass, the height is changed back to its original size (5092 to 5085 twips). However, a side-effect of this sizes change is that the entire view gets invalidated, which causes a redraw.
Note: to see the repaint, you should run with double-buffering turned off (#define in both view managers).
This has been observed on Linux and NT in various builds also. See bug 31986 and bug 32518 I tried to reopen 31986 but Bugzilla won't let me.
I'll take a look.

I'm taking it: it's similar to 32518 and other mouseover problems.
