Fusion Page Dual Screen Panels not showing

Hi,
how do I show the Media Pool, Spline, Keyframes etc panels on the Fusion page in Dual Screen mode?

I would expect them to show up on the secondary screen, but they don't.
Instead the Media Pool, Spline, Keyframes, Metadata and Effects Library tabs, that are at the top of the secondary screen, only turn from grey to white without the panels showing up.

Do I miss something or is it a bug?

Try resetting the UI.

Yes, it seems to be a bug. I had the same problem, and as Igor says, reset UI is a solution for now.

I have a similar issue. Fusion is displaying blank windows when in dual screen mode. It works correctly in single screen mode, but also seems that once you have started Fusion in single screen mode you can then switch to dual screen and it works.
