Separated Mode - Top of toolbar is cut off

[oxjox]

I've tried uninstalling and reinstalling from the App Store. I've tried to change my MacBook's screen resolution. I've hidden and "un-hidden" the toolbar. I've enabled / disabled Integrated GPU.

I can't get the top third of it to display. Or maybe it's just that this icons are shifted up.  The only way I can get it to display properly is to switch to windowed mode (or whatever not-separated mode is called). 

Affinity Photo 1.9.0 
MacBook Pro 13" Mid 2014
Big Sur 11.2.1
Intel Iris 1536 MB

I guess 1.9.1 resolves this issue. Although, there's a horizontal line going through the icons; not sure if that serves a purpose.
