k_len = 2048 and even I tried to have an FFT size 256, I always get
the plot stuck and is hardly updating. No zoom is possible after I run the
estimator.
And after I run that, I cannot Pause nor close. I just have to kill the
process.
Am I missing something or some tuning.

Hi Bastian,
Correct me if am wrong, I inserted a tagged_stream_to_pdu block between the
clock_recovery_mm and the "rxout" pad sink. Isn't that the right way to run
the transceiver script.

BTW the menu bar appears but the blocks, output and the main windows does

I just pulled the changes then did make but get the same error.
I am not so familiar with git. After pulling your bugfix, do I need to make
clean, remove the CMakeCache then do cmake again then make or am I missing
some part of the process.
