I can confirm this bug: I am running Ubuntu 10.10, firefox 3.6.13 with
Adobe flash plugin 10,2,152,27 installed.  My laptop is an HP Pavilion
dv6700, 32 bit.  My primary laptop display runs in 1280x800, my external
monitor runs in 1360x768 to the right.  If the browser is in the right
window and I try to view a youtube video, it appears in my laptop
screen.  If, however, I rearrange my screen so that the monitor is on
the left and my laptop screen is on the right, the fullscreen flash
video appears on the monitor screen.  Fullscreen flash seems to prefer
the monitor on the left.

If, however, I go into System -> Appearance -> Visual Effects and select
NONE, then this problem disappears: fullscreen flash youtube video will
appear in the proper monitor.  This bug seems to be related to the
Visual Effect feature on the desktop.

The priority of this should be raised to at least medium, and the same
behaviour has been noted by multiple sources on the ubuntu forum (see
