Description George Deglin 2007-04-19 14:57:13 PDT
If a flash application is positioned above a scrollable frame, multiple rendering issues can occur. This was tested using a flash movie positioned over a frame with position:fixed on the April 19 nightly and on version 2.0.4 (419.3).

If wmode=transparent:
As the frame is scrolled, the flash movie will remain clearly visible, but it will leave behind a trail on top of the frame. The trail is only a visual artifact, and links under this trail can still be clicked. If the window is resized, the trail will dissapear.

If wmode=window (non-transparent):
As the frame is scrolled a visual artifact of the original position of the flash movie will remain visible. The flash movie will then fail to render any parts of itself except the parts that are undergoing a redraw. (For example, if there is a blinking icon in the flash movie, the blinking icon will appear but the rest of the movie will not). If the window is resized, the flash movie will be drawn correctly until the frame is scrolled again.

Thanks for the bug report, George.  Is there an example of this bug on a publicly accessible web site, or (better yet) do you have a self-contained test that you could post to this bug?

You can see this behavior with embedded Youtube videos in Google reader. As you scroll the reading pane in Safari, the player leaves artifacts all over the window. Camino and Firefox don't have the same problem.

Seems to work now. Duplicate of bug 11768 ?

Confirmed this "ugly" bug in Leopard.

We no longer support Flash (or any other NPAPI plugin).
