286493 - Flash animations draw in the active tab, regardless if they are embedded there

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1

If you send a page with a flash animation on it to the background (or if it
opens in the background) the flash animation keeps drawing over-top of the
current tab. Obstructing anything behind it. The rest of the page content does
not draw over the active tab, only the flash animation.

Reproducible: Always

Steps to Reproduce:
1.Open a page with a flash animation
2.Switch to another tab

Actual Results:  
The flash animation appeared over my active tab (which did not contain the
animation).

Expected Results:  
The flash animation should not be visible until I switched to the tab containing it.

The page I provided uses flash banner ads but only some of the times, you may
need to hit reload a few times before getting one, however this bug is
reproduceable on *ANY* web page with a flash animation.

Using Noia 2 as my theme however the bug has been encountered with the default.

I flagged this bug as security becuase it can be used to draw malicious content
over trusted pages.

Attachment: An example for those who cannot duplicate the bug.

The attachment demonstrates the problem and shows both how annoying it is and
how much of a problem it can pose.

I can't reproduce this on windows (xp sp2) or linux (RHEL AS4). There's a public
Mac bug with similar systems (Secunia.com), but that is really specific to mac.

Unhiding bug to see if we can get some more clues on what it takes to reproduce.

Same problem here running SUSE 9.3. and newest version of Firefox.. (1.0.7) and
flash v. 7.0 r25
I guess that I have had the problem since v. 1.0.5 of firefox but I am not that
sure about this.
Also what is even worse somtimes this problem is followed by a frezze of any
input in the adress bar or in webforms. The frezze can be undone by trying to
close the browser and answer "no" to confirm closing x number of tabs..

Could this be related to bug-report 301500?

I experience the problem with Firefox 1.0.1 and 1.0.7.

Another problem with flash has shown up, when I try to close a tab with a flash
animation in it it often (though not always, even on the same website) crashes
FireFox, possibly related?

Just disabled CX-office plugins (Codeweavers Windows emulator) - I have had no
flash problems today - which is very unusual. Anyone else here using cxoffice or
 maybe Wine?

This is reproduceable on at least two different computers both running SUSE and
CX-Office -- that is the error goes away when I disable all cx-plugins.

I don't think this is a CodeWeavers bug.  I have been experiencing this problem
on Mac OS 10.3.
