Hi,
these are warnings, and you won't be able to use
ctrlport.monitor_performance, but this is not a problem as is.
The Volk warning is just telling you that it's falling back to a safe
implementation, which could be slower in some cases, but will surely work.
To explicitely say it: a warning is a warning that things *might* go
wrong. It is not an error. In most cases, one should not heed it too
much, unless it seems to be related to the problem at hand.

I think you're seeing a single line jumping up and down, and that is
what your data looks like to the wxgui sink.
Try using a larger value for t/s, the < > buttons on the upper button
row on the very left.
Also make sure you're not clogging your CPU with work. If you don't
have a hardware device setting the the sample rate (e.g. a USRP, a
sound card) in your flowgraph, consider simulating that using a
throttle block.

Greetings
Marcus
