I've found another weird behaviour with the Sigil 2.3.0 version on W10 Pro. It's a display problem.
My W10 and linux boxes share a single display, keyboard and trackball. I pass from one to the other by a click on a KVM switch and this has worked nicely for a long time with occasional changes in hardware.
The present combination of switch, screen, keyboard and trackball has been working smoothly for a couple of years. I left Sigil 2.3 running in the W10 to go back to linux Sigil 2.2.1 to check the shortcuts for changing focus between the panes to achieve commonality between the 2 builds.
[ I also removed the attribution of F2 to launch the external HTML editor as recommended in this thread:

because the behaviour was the same as previously noted in linux ]
When I switched back to W10, Sigil had lost its menu bar. I could still access the items by starting with Ctrl+F and using the arrow keys. It was just the display that was affected.
It makes no difference whether the Sigil window is full screen or not. And the time out from W10 to linux seems not to be important. It happens systematically every time I move back and forth between machines.
To get the menu bar back, I just need to provoke the system to redraw by sticking the cursor in the title bar and dragging or by clicking the minimise, full screen icons.
Over the years, I've never seen this with any other application. Would you think it's a Qt problem?
