Using GRC, I just tested changing the sample rate of the fftsink. I
tested this for the gl and non gl version. The x-axis markers move and
change correctly when I move the slider for sample rate. The
flowgraph.grc is attached.
I do not understand why you have the problem? Do you have the latest
gnuradio trunk installed? http://gnuradio.org/svn/gnuradio/trunk
-----------
Also, I am concerned that the gl fftsink aborted/segfaulted. Can you run
the flow graph in gdb and send the traceback?
