Subject: Patch from Mark Wooding to disable GTK's internal double buffering,
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/puzzles/commitdiff_plain/d5b1e2c1dbb25627c99db211476d4eb01c66f744

Patch from Mark Wooding to disable GTK's internal double buffering,
which I didn't know about, but which is clearly a waste of effort
since we keep our own backing pixmap for the puzzle window.
