Black colored objects show old flash video

Hi -

On occasion, after I watch a flash video on youtube in firefox, the final frame of the video (specifically the one with a replay button and a few other suggested videos) will remain "stuck" on the background of my desktop, but it is only visible through something colored totally black. For example, the black background of a terminal window or the text of a website. It is not set on the actual desktop background - just any time something should be black in the location of the old video, the final frame appears. When this happens to black text, the text just looks like parts of the font are missing (corresponding to the white parts of the video).

Any ideas what this might be? I've only seen it on one of my machines:
Intel Thinkpad T61
2.6.36-gentoo
x11-drivers/nvidia-drivers-260.19.26
www-plugins/adobe-flash-10.2.161.23_pre20101117
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.13) Gecko/20110106 Gentoo Firefox/3.6.13

Thanks.

Have the same problem on my cpu, amd64 and some nforce on abit motherboard.
My mouse chops when play videos on youtube, and all other flash video is working "something like flash games etc.." but is blurry from last frame from youtube. It happened to me when I changed or add some USE flags in /etc/make.conf, never before!
"directfb 3dnow 3dnowext firefox firefox3 flash flv objc++" or dont know
Now look at the last youtube frame under transparent text you type here

please help is disgusting.

hire is some of my configuration:
CFLAGS="-march=athlon64 -O2 -pipe"
CXXFLAGS="-march=athlon64 -pipe"
USE="3dnow 3dnowext 64bit X alsa audacious audio automount \
bzip2 cache ccache cdparanoia cdr consolekit dbus directx dvd dvdr \
dvdread firefox firefox3 flash flv ftp fuse games gif gimp gkrellm \

There are a couple of other threads about related problems. Downgrading to adobe-flash-10.1.102.64 solved the problem for me. The latest security alerts say this version is unaffected by the security vulnerabilities that affect earlier versions.

Thanks but i was convinced that it is not up to it because using stable amd64 sources, and something i changed in my USE flags.
All twentyfirst century can be the...

Thanks again.

Quick way to fix it is to CTRL-ALT-F1 then CTRL-ALT-F7 (switch to console and back to X) - corruption disappears.

I also have the same problem.

I have:

adobe-flash-10.2.152.27
nvidia-drivers-260.19.36
firefox-3.6.15

wolfram

Mike of NVIDIA noted that the Adobe flash plugin uses black as the overlay color, likely related to this issue.

An approach, possibly similar in EFFECT to Ctrl-Alt-F1 followed by Ctrl-Alt-F7 as described by lyallp, is achieved with (modified from Jack Waterworth of RH):

1. Right click on the youtube video --> select settings
2. Disable hardware acceleration
3. may need to close the command window <--- not verified
4. reboot (or restart X) <--- may not be necessary
5. Enable hardware acceleration. <--- seems to be ok

I found step 4 not necessary and subsequent ACTIVATION of the hardware acceleration did not return the defect.

Is this an on-going fix or does it need to be repeated every time the machine is started?

Unfortunately I cannot change my settings, I right click, the little window appears but it is totally unresponsive, as though it's not there.

I should mention I am running www-plugins/adobe-flash-10.2.159.1 and x11-drivers/nvidia-drivers-270.41.03
Oh, and I see the problem on 32 and 64 bit systems in Firefox 3.6.17.

Suggestions would be welcomed.

I had the same problem some time ago but it had gone for long time.
Unfortunately the problem came back with newer versions of nvidia and flash (I'm not sure which one). After system update I see flash in background of my console and on other tabs :/

Got versions:
www-plugins/adobe-flash-11.2.202.235
x11-drivers/nvidia-drivers-295.49

EDIT:
solution for that is setting WindowlessDisable=1 in /etc/adobe/mms.cfg
