If windows are appearing to become black (eg, they open and are black)
then AMD needs to be alerted of this since it means that the driver
has run out of video memory to put pixmaps into.

Copytexturing might be an option to look into here, however that is
probably going to be for O and not N at this stage.

That's because you've got 2x2 workspaces. Cube only works for
horizontal workspaces, so you've got a 2 sided polygon in that case.
