Are you using the threaded rts? Are you linking the program with
-threaded?

Are you doing the drawing directly in the timeout function or just
invalidating the window/widget and letting it get redrawn?

See for example the cairo clock demo which animates the hands of the
clock every second:

timeoutAdd (widgetQueueDraw window >> return True) 1000

In general it is much better to only ever draw to a window or widget
during that widget's expose event.
