Plasma freezes related to Desktop Theme

I am only testing F22 thus far in a Vbox VM. I would appreciate it someone could try this on real HW. I found that if I install the Desktop Theme "Polished Stones" that almost anytime I get a notification in the systray the tray will become non-responsive for several minutes. Cannot use the launcher for example. It can be tested by "getting new themes" searching on polished and installing "Polished Stones". Then starting firewall-config from the launcher. Thanks -- Sorta what I want to say when folks habitually complain about Fedora - https://youtu.be/ZArl8fTfub4
