           Summary: Flash video doesn't respect z-index with accelerated
                    compositing enabled
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://www.test1.easyprowebtools.com/
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jhoneycutt at apple.com


This is broken out of bug #38443. The page has an iframe with Flash video that uses wmode=transparent so that the page's menu can use a higher z-index to composite on top of the video. However, if hardware accelerated compositing is enabled, the menu appears under the Flash video rather than overlaying it.

To reproduce:

- Ensure accelerated compositing is enabled
- Open the above page
- Mouse over the text "HOME", which should show a menu on top of the Flash video

If hardware acceleration is disabled, the menu overlays the video.
