That happens in the QMovie::current_frame() call where the frame is prepa=
red=20
and send to the X-server. It doesn't lock up the X-server of course, but =
it=20
certainly causes traffic. Just like a regular mouse-over causes tarffic, =
only=20
this time it is more prolonged.

The biggest performance problem is probably just the disk-access for open=
ing=20
the movie. That's not a problem when your system is idle, but when you ha=
ve=20
pressure on your io-system it might take a while. In that case it would=20
probably make the UI jerky.

Cheers,
Waldo
