@Waidhoferj There is this code in your drawing example:

Lines 28 to 31 in 792dc96

    
           # Sometimes transactions don't write, which means updates are empty. 
        
           # We only care about updates with meaningful mutations. 
        
           if update != b'\x00\x00': 
        
               self.send_q.put_nowait(update)

Why are empty updates emitted? This creates issues here and there.

	# Sometimes transactions don't write, which means updates are empty.
	# We only care about updates with meaningful mutations.
	if update != b'\x00\x00':
	self.send_q.put_nowait(update)

Empty updates
