Bug Description

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.

Confirmed with karmic, seems to only happen if you use 2x2 viewports. Very odd.

Just checked: With 2x1 and 1x2 it's a little different but still there: With 2x1 there is horizontal wrap only, with 1x2 only vertical.
With anything >= 2x2 you get horizontal+vertical wrap ( the full torus ).

Thread in compiz forum (no answer so far):

This is still existant in Oneiric.

I don't know but this might be intentional.

Looking through the unity spec, I cannot find anything on whether workspaces should be separated or interwoven. Asking for the design team for input.
