Hi Søren,
thanks for your tests.
I think the delay in plotting only takes place the first time (at least 
it was so till now for me on many win7/win8 pcs). The following plots 
are quick. I imagine it depends on some sort of first-time house keeping.
On the contrary, I have never seen this "partially out of screen" issue.

Can you please save the figure as a pdf file, then open it to see if the 
plot is well drawn?
I tried with the "sombrero" surface and with the simple x=1:10; plot(x, 
x.^2) stuff, obtaining empty axes as the pdf file (on some installations).

Thanks
Giorgio
