In any case,
When I close any dialog popup from java apps (Jdeveloper, NetBeans, SQLDeveloper) then I get gnome-shell running at 100% of processor and graphical interface hangs.
I've checked for my mutter installed version:
3.32.2+git20190626-1ubuntu1~19.04.1 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_disco-proposed_main_binary-amd64_Packages) (/var/lib/dpkg/status)
Downgrading mutter and libmutter as Iliyas indicated, I can avoid the problem.
Thanks to Ilyas and thanks to everyone.
