Thanks, do you think that there is a hard limit on this approach and use for the frame updates to about 24fps?
and the Gtk.Canvas dimension settings seem to ‘crop’ the images… is it best to then do the scaling from the Cairo scale function each time there is the painting/drawing?
As well, I get a Gtk-WARNING **: drawing failure for widget 'GtkBox': out of memory from the use of Cairo.scale(ctx,.5,.5) on repeat, although I redraw the rectangles and images from .png images
