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

The problem stems from the fact that too much of the internal
machinery in the wxGUI graphical sinks are computed in Python.
For long FFTs, and even modest update rates, those computations take
longer than is strictly healthy for dealing with the arrival of
new samples, so the GUI thread gets wedged.
Again, given the fact that your display geometry is likely less than
1280 wide, you'll simply lose information for FFTs larger than that.
But I've
already said that.
