Pepper Flash Plugin Produces Black Boxes On-Screen

[Google Code Exporter]

What steps will reproduce the problem?
1. Loading the page will frequently reproduces the problem.
2. Disabling Flash, via Flash Control Chrome Plugin, and re-enabling will 
frequently reproduce the issue.


What is the expected output? What do you see instead?
We're expecting to see the web page fully loaded without displaying unintended 
black boxes on-screen, obscuring content. Instead, the page loads and is 
partially, or sometimes fully obscured by black boxes. A click on the page will 
cause the boxes to disappear. 

What version of the product are you using? On what operating system?
Chrome 21, though a recent update to Chrome 22 and the issue persists. Windows 
7. 

Please provide any additional information below.
We have been able to isolate the issue using a few methods. By preventing Flash 
movies from playing, and/or by preventing Flash ads from loading, we can 
prevent the issue.

Using jw player Ver3.0 and 4.0, a problem arises.  
We use Windows XP.  
Before a playback screen displays, a black box is reflected for a moment.  
Using IE or Firefox, a problem does not occur.
Using Chrome Ver22.0.1229.94 m, a problem occurs.

This is still an issue. NPAPI Flash plugin will soon be deprecated so I checked 
to see if pepperflash had improved in the last 2 years and it has not. Adobe 
plugin does not have this issue

Windows 7
Chrome 39.0.2171.71 m
Pepperflash 15.0.0.239
