Just installed and I have an interesting issue.
Everything works fine, except on my 28" main display, I get all this weird looking stuff on the background. On my 20" secondary display I don't. All the fish and scenery displays fine.
Running on a core2quad
Vista x86
nvidia quadro FX3400 (driver dated 12/17/09)
I disabled the secondary monitor, disabled aero theme, went down to 800x600, but nothing changed it.
I do quite a bit of rendering in autocad, and have never seen anything like this before.
I rotated the image so it wouldn't make the forum display so wide.
