i was reading gnome-shell manual today and i have found out:
Alt+F2 allows entering a command to launch an application. If you want to launch a shell command in a new Terminal window press Ctrl+Enter.
So basically, you should run command in new terminal window (Ctrl+Enter) instead of just "enter".
So from byobu side, there is nothing what we can do.
