Ha, I kept digging and in the end found that them problem is caused by InvertColor in DrawDragFrame (probably it is not possible to implement difference operator with Xrandr, so cairo needs to copy memory chunks from/to GPU).

As using that is not mandatory, e.g. alternating white and black dots work as well, I have removed InvertColor and the whole thing started to work as expected. Gtk3 for repeated image draw are now in microseconds range.
