Most likely other folk have reported the same issues, so I will keep this brief.
Display issues. Lines appearing between drop down menu options.
Menu issues. Menus vanish within seconds making it hard or impossible to use them.
No way forward without deactivation.
I assume a new release is on the way.
Although, it actually looks as thought WP is FINALLY incorporating many of Fluency's excellent features into the core. Nice to see. Always wondered why they didn't take the lead from Fluency and improve the layout.
