> After I've added a call to this method at the end of my program there's less "leaks", but some remain. Apparently the memory is allocated by certain pixman methods (stack trace attached). Maybe there's a method similar to cairo_debug_reset_static_data in pixman, too? I failed to find it so far. Or does it mean that something actually went wrong?

Pixman does not provide a function to cleanup the caches.
