As pointed out by someone on IRC, this bug is only reproducible if you run your webbrowser in maximized mode.

I see this as invalid, since it's the same as pressing Page Down, then Page Up, which causes the same scrolling behaviour, and "default" pass includes not scrolling the test. When the browser is the full height of the screen, this causes the document to scroll, when the browser height is half the screen size, both zoom in/out and page down/up don't mess up acid2.

As an end user, I find it unintuitive that elements within the page changes their *relative* position when I scroll up and down a page? I'm not familiar with the technical details of how this test is constructed though.

This is likely not a bug. The two bits you see are fixed positioned, and the rest isn't, so if you scroll the page you'll see those bits stay in place while the others move. If you zoom out and then zoom back in you are likely changing your scroll position.

That's what position:fixed means :)

Erm basically in my bug ( Bug 418235 ) I'm asking for the Acid2 test to work on all zoom levels. My argument is not to pass the Acid2 test but so people who need zooming to work should have it work correctly on even awkward web pages. Here's what I wrote:

"Here's what the acid2 guys have to say on zooming in Opera 9:
http://www.webstandards.org/2006/07/20/acid2-and-opera-9-clarifications/

The basic gist of which, is that while zooming should keep a nice smiley face
it's not a prerequisite of the test.

But that's not really the point here, people who 'NEED' zooming to use the
browser should have it work well even on incredibly awkward pages."

I'm fairly sure this bug can be moved to Core::Layout and moved to Trunk.

I reopened bug 418235 to cover issues other than scrolling.  The only one I noticed was the background behind the eyes being a pattern of yellow/orange/red rather than solid yellow.
