I'm using Ubuntu 14.04, UHD_003.008.00-18-g864f84b5 and GNU Radio 3.7.6
Whenever
I start uhd_fft from a command line, the window opens and starts to
plot. After about a second, the window goes into not responding mode,
where it greys out and you can't click anything. Does anyone know what
could be causing this behaviour? Is it a local setting of mine?
