I experienced problems when using a Drawing Area with animated pictures.
I get the tearing effect, that is, half of the picture shows the old
frame and half of it the new one because the update occurred during the
cathode ray being in the middle. I used SDL before, but I want to use
standard widgets, too. It would be possible to map a SDL_Surface to a
gtk_widget, but only under linux and I want my program to be portable at
least to windows and linux.
I attached a simple program to show the effect. Although it is written
in GTKmm, this is a problem of GTK (perhaps it is not even a GTK
problem, but it works with SDL and there has to be a possibility -
perhaps someone can please help?)
