Aha! I hadn't clicked on other tabs, but the current one is blank.

I don't allow moving tabs and the title remains on the frame when I move it
(I run Slackware64-14.2 with Xfce4 and its default wm and PyQt-5.13.2).

Nope. I'm doing one thing at a time. After I fix this blank current tab I'll
go through each module and group widgets when it makes sense to do so, then
validate data entry, set widget sizes, and emit signals and write the slots.

This may be the case. I've not yet specified fonts or colors and when I do
so this issue might be resolved
