803793 - Black Rendering With Adobe Flash Plugin

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect, P3)

Description

[Alex]

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:19.0) Gecko/19.0 Firefox/19.0
Build ID: 20121018113029

Steps to reproduce:

1. Opened up Firefox Nightly.

2a. Minimized and then maximized window.
2b. Re-sized the window.


Actual results:

Firefox shows blackness for webpage content and nothing for the interface, but flash player is shown. Then, some time later, Firefox shows the webpage and shows its user interface.

Reproducible on W7/8 32/64, various drivers, DWM enabled.


Expected results:

Firefox should not have presented the blackness and blank GUI.

When resizing the unrendered parts of Firefox should be white, not black, like they are without flash elements present.

It's likely an issue with the latest version of Flash, I'm able to reproduce in FF16 and FF8.

Same result with HWA on/off in Firefox.

I can see the slowness, but I don't think we'd track if it's not a Firefox regression.

Alex, did you try to reproduce the issue with a previous version of the Flash plugin? (like Flash 11.2, before Flash 11.3/11.4 and the protected mode)

I first noticed it at time of Firefox 11. AFAIK, that was before Flash 11.3, but not sure.

Flash is no longer supported.
