Firefox plugin overwrites root window

[Gordon Ball]

Binary package hint: firefox

ubuntu 10.10, i386
xorg: 7.5+6ubuntu3
nvidia driver: 260.19.06-0ubuntu1
firefox 3.6.15+build1+nobinonly-0ubuntu0.10.10.1
metacity 2.30.2-0ubuntu1

After running flash content in the browser, the last frame shown remains in some part of the graphics buffer, and bleeds through into black pixels of any window moved on top of it. (ie, a semi-black background image shows the last flash frame only in the black area, and a terminal moved over the area shows the last frame everywhere except the white of the characters).

I had originally assumed this was getting drawn onto the X root window, but the effect is not stored in screencaptures with either gimp or xvidcap. Killing firefox/plugin-container does not make the effect go away. Restarting metacity does remove it.

I don't know if this is a bug in the flash plugin or plugin container (presumably related to hardware acceleration/DRI), or somewhere else in the X stack. Does anyone have suggestions for more useful diagnostics?

I have same problem.

Effect starts eg viewing a youtube video, then the video bleeds through any fully black pixel. -- occurs even while the video is playing, you can watch the video it through any black object (eg viewing an all black image in an image viewer)

Killing firefox doesn't clear the buffer. Reboot does.

Turned off compiz, but no change even after reboot.

(How can I restart metacity?)

ubuntu 10.10, nvidia driver 260.19.06, firefox 3.6.15, metacity 2.30.2

I have the same in Opera browser and Chrome, probably it's the issue of flash plugin, not of firefox.

If we do not hear from you the bug report will close itself in approximately 60 days time.

Thank you for helping make Ubuntu better.
