The strange thing is that when the fft's sample rate is at 25Msps which
equals the USRP's bandwidth at a decimation of 4 everything works fine with
the regular fft sink yet not with the OpenGL one. However when I increase
the fft's sample rate to 50Msps which is 2x the USRP's bandwidth both sinks
work fine. What does this mean?

I'm really convinced all this is because graphics are rendered strictly
through software. Does GRC even support graphics hardware acceleration? how
do I configure it?
