I been noticing this with D3D9 using this URL - (http://thebubble.msn.com) on a 1024x768 screen in maximized mode while testing bug 579597 (large enough the plugin overlaps the scrollbar, scrolling up and down I can trigger it)

Horizontal scrollbar almost appears to be transparent when it first loads the plugin.

But then I noticed it will occur with Youtube WebM video as well if the window is sized correctly. 

Basically the horizontal scrollbar is covered up by the flash plugin or WebM video on Youtube if it bisects the plugin area - basically I make the window small enough so that the horizontal scrollbar overlaps.  You'll see by the attached screenshot, it doesn't even have to be playing for this to happen. Since it will be that way once the video stops. 


Not a problem:
Its not a problem if I disable D3D9.
Though Youtube Flash doesn't look like it is affected.

Whats interesting is that vertical scrollbar doesn't have this problem.

Comment 4

[Joe Drew (not getting mail)]

It makes me sad, but it's only the horizontal scrollbar. I want this fixed, but I think we can release without this fix.

Comment 5

[Robert O'Callahan (:roc) (email my personal email if necessary)]

I think we should try to fix this. It's unlikely to be just the horizontal scrollbar, it's likely to be a fundamental layer rendering bug.

Comment 6

[Bas Schouten (:bas.schouten)]

I can reproduce this. The regression window is certainly interesting. I agree with roc that this is indicative of a more fundamental rendering issue.

Comment 7

[Bas Schouten (:bas.schouten)]

This will be fixed by bug 614651.
