Hi
I have installed Ubuntu 18.04 and GNU Radio 3.8 on two
different computers several times using these commands from
https://wiki.gnuradio.org/index.php/InstallingGR#Ubuntu_PPA_Installation.
sudo add-apt-repository ppa:gnuradio/gnuradio-releases, (or
sudo add-apt-repository ppa:gnuradio/gnuradio-master)
then
sudo apt-get update
sudo apt install gnuradio
But each time my flowgraph runs with the following warning:
<<< Welcome to GNU Radio Companion 3.8.1.0 >>>
Block paths:

My flowgraph runs but I have seen some effects that shouldn't appear
(e.g., FFT of a cosine doesn't have two simple impulses) and perhaps
GUI not updating properly. How can I fix this problem?
Thanks.
The XinitThreads() is just a warning.
Without seeing your actual flow-graph, and the results, it's rather hard
to comment on the rest of your problem report.
