[GnomeMeeting-list] Re: Excessive CPU usage if videos are in their own window

[Filippo Polo <filpolo tin it>]

I am not sure; I will check as soon as possible. Either way, why would USB cause a huge CPU difference between rendering the image in one window, or in two windows? That's what I don't understand. If it takes 35% to see two images in one window, it should take 36%, top, to see the same two images in two windows.
