Not really noticable here, unless I middle-click mousewheel, and then scroll diagonally. (same build)

Load several tabs - MSNBC.com on one tab, CNN.com on another.  Switch to another tab, like bugzilla, or the t-box page.  Scroll around on any page.  Switch now back to MSNBC and note the weirdness and graphical elements appear on page as you mouse over the page.

Download dialog painting issues, too.

Over to me; I didn't notice anything on my XP system while testing, but I'll try on Vista now.

Attachment: patch, I think

Ok, here's a patch that I'm going to check in in time for tomorrow's nightly.  I'm not entirely happy with it, but it seems to fix the problem and is more-or-less correct.

Thanks for the screenshot btw -- using the menus was a lot easier to reproduce than doing it with web pages :)

Checked in; let me know if this still happens (I guess I'll find out tomorrow)... if it's fixed, I'll have to revisit that "this should never happen" comment :)

I just downloaded the latest hourly, and been using it about 45 mins now, and so far looks OK to me, no more paint issues.  

Some with a keener eye than mine may want to verify as well.

Should we clobber to prevent more reports?

I think I got it in before the nightly; folks have been testing with the hourly builds.

Yep - you did.  Nevermind
