A reduced testcase will be the first thing we need here...

More minimal than this?

I guess you can nix the background-attachment and background-position and background-repeat bits in that testcase...  So one that's smaller coming up.

But nixing the solid background color makes things suddenly work.

Not entirely sure what the bug here is, but it's fixed by the first patch on bug 798964. Trying to get the last few test failures from that fixed now.

Removing the "testcase-wanted" keyword as one was provided in comment 4 and comment 6.

Thanks,

According to the TC in Comment #5 and Comment #7, this is working -- let's close as FIXED (apparently fixed by Bug 798964).
