The emulator simulates the eInk refreshes, but only in part. The scribble system draws directly into the screen buffer, bypassing GTK. Only after a real dislay update is triggered, the strokes are visible. We have a fix underway to draw the strokes on a pen-up in the emulator. It's not quite the same but it is closer to the actual device.
