Attachment: testcase

See testcase, when scrolling down and then up the overflow:scroll div, I get horizontal black stripes, this is probably related to/the same as bug 370444.
It also has a regression range between 2007-02-06 and 2007-02-07, so probably a regression from bug 177805 too.

Marking worksforme.

Sorry, I was too quick!
I can still see these black horizontal stripes appearing in current trunk build.
But now they happen when scrolling upwards, when clicking on the 'up' button.

This is a regression since the first week of February and unchanged until now (click in div - scroll down with wheel - scroll up quickly.) Does not succeed with all mice here.

Some places now get horizontal black lines like here:
http://www.hegnar.no/default.asp (well esteemed financial publication in Norway)
Other places get white lines over images:
http://www.shinyshiny.tv/ (much quoted gadget site)

A forced reflow makes the lines go away (resize window or select all/deselect etc), but scrolling with mouse or slidebar again spawn new lines. Which way I scroll doesn't seem to matter.

Sorry if it's the wrong dept. I've half lost track of who's around. But this is an ugly little regression..

FWIW: black lines/stripes at http://www.hegnar.no/ are now gone, 200707180808
Saw a checkin that likely fixed it around a week ago, but can't find it again.
(White stripes remain but is another bug)

I can't reproduce it anymore with current trunk build, so marking worksforme.
