Virtual desktop weirdness: Screen space wraps around (window moved across edge of one virtual desktop appears on another on opposite edge)
Binary package hint: compiz
I use 2x2 virtual desktops.
When i move a window across the right edge and the bottom edge of the bottom right virtual desktop, the hidden window parts appear on the other three desktops - the top and bottom, left and right edges of whole screen space are interconnected as if the would form a torus. ( see desktop-torus.pdf for screenshots )
This is annoying and weird. With desktop effects off the problem goes away.
Ubuntu Jaunty, compiz 1:0.8.2-0ubuntu8.1.
