Hi
I'm finalizing an in tree QTGUI eye_sink block. I use a GRC
example which was working fine until I decided to upgrade my local
GNURadiorepro (GnuRadio and Volk upgraded to latest commit on
January 5 2020, I was previously using 3.9 master uploaded in
November 2019 ).
May be this can be related to
this commit ... but I did not succeeded in solving the
issue.
Regards, Christophe
