Subject: Patch from Mark Wooding to disable GTK's internal double buffering,
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=9ce82b0feb6f19c6246198f957ed60edf2a11720;p=sgt-puzzles.git

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.
