Hi everybody, 

I have a problem. 

Yesterday I installed Fedora 20 (x86_64) laptop the following, bladeRF from nuand, and UHD + GnuRadio + gr-osmosdr + gr-iqbal etc... using Marcus Leech's build-gnuradio script. 
"$ wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio" 

I know have installed the following versions. 

1) bladeRF: 
libbladeRF 1.4.0 
bladeRF-cli 1.2.0 
FPGA: 0.3.0 
Firmware: 1.8.0 

GnuRadio 3.7.7 
UHD 3.9.0 

I am running the osmocom_fft utility on both the Ettus B210 and the bladeRF. 

osmocom_fft -a bladerf=0 -s 1M -f 947M 
osmocom_fft -a uhd -s 1M -f 947M 

Both seem to be running fine except that the GUI does not look correct. 

Please see attached images showing two screen shots of the osmocom_fft GUI. 

Nuand bladeRF: Center Frequency and Gain Settings are messed up. Text and sliders missing, and the boxes with the actual values are not in the right location. 

Ettus B210: Center Frequency and RX Gain are messed up.Text and sliders missing, and the boxes with the actual values are not in the right location. 

Side note: uhd_fft runs without any problems (on the B210) and the GUI looks correct. Nothing is missing or in a strange location on the screen. 

What can be causing this? How can I fix it? 

Thank you for your consideration 

Reagards,
