(Firefox :: General, defect)

Description

[Tonio Loewald]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

The attached URL displays a flash move in a layer floating above an iframe that
fills the window. The flash animation flickers slightly and does not receive
mouse events. The same problem occurs in 1.6a1 and Mozilla.

The same page loads and runs perfectly in IE.

Reproducible: Always

Steps to Reproduce:
1. Create a page containing an iframe with an overlapping layer containing flash.
2. Observe the behavior of the flash movie (w.r.t. mouse interaction) where it
overlaps the iframe.
Actual Results:  
The flash movie does not get mouse events.

Expected Results:  
The flash movie should get mouse events (and should update cleanly).

I reproduced this in 2.0a2

Also occurs when one embeds a swf (with wmode=transparent, like in the bug reporter's examplle) in a page containing a full window iframe to another page. Works fine in IE, and works fine in Firefox with transparency disabled.

I can also confirm this bug. The IFRAME does not need to be full page. However the flash must have a WMODE other than the default of "windowed".

Pre-2.0.0.2 a workaround for this was to use position:fixed (Which for some reason averted this problem), and then to move the movie as necessary with javascript. Unfortunately, this workaround is now blocked by Bug 374497.

Do you still see this problem using latest version of Firefox and Flash (10)?

If you do, please comment.
If you do not see the problem, please close the bug - don't use resolution=FIXED, change resolution to:
- INVALID if you believe the problem was flash player
- WORKSFORME if you believe the problem was in Firefox
- INCOMPLETE if it is impossible to test (url or testcase is gone)

Need testcase or URL. I never saw this with my machine on WinXP, a testcase or URL would be nice so I can try on Gentoo as well.
