When watching any flash video (embedded or not), there is always a green bar that appears at the top of the video. This makes the video very undesirable to watch. This happens on any version of Firefox, not just beta. I believe the problem is probably just on my machine and it probably relates to plug-ins but I tried with a fresh profile and the same thing occurs.

Steps to Reproduce:
1. Launch Firefox
2. Go to youtube.com
3. Watch a video

Actual Results:
The video quality is poor and there is a green bar at the top of the video. Please see screenshot.

Expected Results:
Video plays properly with excellent quality and no green bar/artifacts of any kind.
Is this youtube via flash or html5 ?
What is your flash version ?
Does it happen in the Firefox safemode ?

This is youtube via Flash. It doesn't happen with HTML5. This problem occurs in most flash videos and not just from youtube.

Flash version is 11.2.202.233.

Yep, it happens in safe mode too.

This looks like a bug in the flash plugin together with your graphic card driver.
Does it work in other npapi browsers with the same plugin (all except IE, select the external instead of the internal flash plugin in Google Chrome)?
Does it work if you disable the hardware acceleration in the flash plugin ?

That seems to be exactly the problem :)

I get the same problem in Chrome when I use the external Flash Plugin.
The problem goes away in Firefox if I disable hardware acceleration.

Is there a way this can be fixed in FF without having hardware acceleration turned off?

Thanks!
>The problem goes away in Firefox if I disable hardware acceleration.

I assume that you mean the hardware acceleration in the flash plugin and not Firefox.
The Firefox safemode disables the hardware acceleration in Firefox and you confirmed that the green bar doesn't disappear in the Firefox safemode.

this can't be fixed if this only disappears with disabling the hardware acceleration in the flash plugin. This can be fixed only in the driver or the plugin.

I often get ugly double images with a green tinge and sometimes green flashing with Flash Videos (with Flash HW Acceleration on). This started a couple of Flash versions ago (so the Bug is not ours, AFAICT).


Fix (for me was):

1. Right-click on a Flash Video and choose [Settings][Display] and un-check "Enable hardware acceleration".
2. Download "YousableTubeFix" (for GreaseMonkey) http://userscripts.org/scripts/show/13333
3. On a YouTube Video Page (ONLY) you will have a [Configure] Button below the Video, click it, then the [All Pages] Tab.
4. Go to the last setting (Flash Player wMode) where there are many choices including "Direct Mode (hw accelerated, recommended)" and "GPU Mode (hw accelerated, no guaranteed pixel fidelity)" - both work great for my old Computer.

There are also many other useful features to play around with including 'stopping autoplay', many 'preset video sizes', choose 'default video quality', blocking (Ads or portions of the Page), enable 'Download Button' etc.


@Matti: I suggest changing the "Product" and "Component" so an email gets sent to the people who work with us (at Adobe) on Flash issues (as those are currently set to the defaults).
