Running the current SVN I'm having a problem with apps that display
multiple scopes (usrp_nbfm_rcv.py) for example. What happens is that
the application will update only a single scope at a time. One scope
updates for a couple of seconds then another scope does, in a round
robin fashion. The GUI is mostly unresponsive. I see no
overflow/underflow, the audio runs fine, only the GUI is screwy.
Switching the app to one scope resolves the problem. Top is reporting
the app only using ~30% of a cpu on a dual core box.
I had this problem some months previously but it was intermittent and
I thought it might have been some power management glitch slowing down
my system since I was running on a laptop.
I'm at a bit of a loss as to where to begin troubleshooting this. Suggestions?
