Marcus,
I have tested this under the Ubuntu LiveUSB on a couple of machine and the same
problem occurs every time.

Marcus,
Accurate output is great when doing analysis, but if you just
want to create a quick interface that will allow you to see a
little more detail, then overlapping or duplicating the stream
is fine. The error in the output is always within a given
tolerance and that can be suitable for a lot of applications.
By no means am I suggesting to eliminate the accurate GUI
elements, just that an alternative should be offered.
I tested your sample and that works fine on my machine. I have
updated it to a refresh rate of 30 and this is when it becomes
unresponsive. I ran perfmon and the resources seem fine, but I
do see a massive spike in page faults and transition faults when
executing a flow graph. That, in itself may not be an issues,
but I have checked all the usual bottlenecks and they are barely
being touched. I'm running the latest Windows build of this on
a quad core Win2012 server with 16GB ram.
It seems like a bug in the build.

More likely a bug in the Windows wxGUI implementation, which is
known to have lots of flaws.
I assumed you were running this on Linux, which is the primary
development platform for Gnu Radio.
