Qt frequency sink very slow

Hi all, I update the gnuradio from 3.8 to 3.10 on ubuntu 20.04 lts. Every think is working well except qt frequency sink that now is very slow and not respond to update rate adjustments. Waterflow working fine. Do you have some issue? Ciao David

Re: Latency due to hardware initialization

Hi Ahmad, I think both, sink and source, start consuming/producing samples as fast as they can. If the buffer for a hardware sink runs empty, you will get "U"s printed in the command line, for under-run. If a buffer after a hardware source runs full, you will get "O"s printed, for over-run. If
