I imitated it with a short night shift duration and see no problem. Please can you add a screenshot how it looks after the change to daylight? Does this partial dark mode stay when you restart TB?

Screen shot attached of default day screen. I can change to the light theme by enabling the light theme and then the default theme (keeps light theme). This does not change back to the dark screen by enabling dark mode and then default mode - in fact keeps light theme. Restarting TB keeps day screen. No problem in evening of move from day to night mode.

Hmm, here it works flawlessly. Alessandro, what do you see?

I think I'm having a whole other problem.
Manually switching the macOS settings from dark to light correctly updates the Thunderbird Theme.
If I set the theme to Auto in macOS, and then manually change night shift to force night time, the OS doesn't update at all unless I log out and back in. Thunderbird follows along.
On my end it seems that Thunderbird follows the settings of the OS correctly, but the OS doesn't properly follow the night shift settings.
I'm on macOS Catalina 10.15.2

Hmm, tricky that it's not on every system the same. Firefox has some issues too, see bug 1558086. As we use the toolkit code from Mozilla, we can't do too much here and have to wait, and hope, FX finds a solution.
