This picture shows a black patch and this is caused by zooming out and scrolling. The non-black patches are where my gimp was, there was a black rectangle all over the text ( not the blue border )

The ui doesn't allow anymore to zoom out extremely, but I can still see this bug in current trunk build with this testcase. It uses enhanced privileges, so you need to download it to your computer. I'm also seeing these assertions with the testcase: ###!!! ASSERTION: reflow state computed incorrect width: 'reflowState.ComputedWi dth() == size.width - reflowState.mComputedBorderPadding.LeftRight()', file c:/m ozilla-build/mozilla/layout/base/nsPresShell.cpp, line 6144 ###!!! ASSERTION: Invalid computed height: 'aComputedHeight >= 0', file c:/mozil la-build/mozilla/layout/generic/nsHTMLReflowState.cpp, line 285 ###!!! ASSERTION: reflow state computed incorrect width: 'reflowState.ComputedWi dth() == size.width - reflowState.mComputedBorderPadding.LeftRight()', file c:/m ozilla-build/mozilla/layout/base/nsPresShell.cpp, line 6144 ###!!!

ASSERTION: Invalid computed height: 'aComputedHeight >= 0', file c:/mozil la-build/mozilla/layout/generic/nsHTMLReflowState.cpp, line 285 I don't see any crash, though.
