That is exactly what I did. About the noaccel mode,
if that is the default you could be right. There was
an option in the xorg.conf (generated by X -configure)
about that, but it was disabled. I did not find any
information about options for nouveau in the Arch
wikis or any other places. 

Apart from that, I don't see why even an unaccelerated
driver would require a second or so to slowly swap 
foreground and background, going from the top of a 
window to the bottom, and one more second again to
undo that. A single fillrectangle with xor action does
that faster than you can see it.

Finding out that 'X11ForwardTrusted' was not just
about authentication but could actually impact speed
*was* as surprise !!
