Brecht,

A question about partial redraw, can it be set up to have multiple
drawing regions? In sculpt mode with symmetry, there may be only small
parts being sculpted, but if these regions are at the four corners of
the screen and it's all combined into one large region, much of the
benefit of partial redraw will be lost.

BTW, triple buffer works well on my system (ATI radeon).
