Slow to refresh screen

Ive been using my Touch heaps and love it. One thing that is bugging me is that under "Settings" when you can remotely see the profilux screen it seems to refresh very very slowly and i get lines.

Is it just the speed of the data going through PAB, is there a way to increase it???

Otherwise all good for me :)

the communication of sensors, sockets and all other important devices related with the tank's security have priority on the bus

the Touch gets already the maximum possible bandwidth

-> can't be improved at the moment without changing the whole communication concept
