I committed some changes. Fullscreen indeed causes the Nvidia driver 
to go from swap copy to swap exchange. "Overlap" then needs to run 
with the -E command line option to work correct.. will probably remove 
this method or enable -E by default eventually. However for "Triple 
Buffer" I would not expect it, but it may be because it is falling 
back to "Overlap" because it failed somehow, is there a message about 
this in the console?

This is due to an SDNA bug, worked around it for now.

Thanks. "Overlap" flickering probably is due to not using the -E 
command line option. Good to hear Triple Buffer works.
