[Bug]: UI Mode behave incorrectly on macOS

[lucydodo]

What did you do?

We've seen some issues with 'Dark Mode' recently, so I tested for all cases of UI settings in macOS and in our app.

What did you expect to see?

Consistent UI experience

What did you see instead?

App UI Setting	macOS UI Setting	Screenshot
Auto	Light
Light	Light
Dark	Light
Auto	Dark
Light	Dark
Dark	Dark

I think (but haven't checked the code flow yet) that if user set it to 'Follow the desktop UI', the UI changes are made by the Qt framework, and if user select the 'Light' or 'Dark' option, the changes are made by the other stylesheet.

DB4S Version

3.13.99 (nightly)

What OS are you seeing the problem on?

OS version

Oh that looks weird. We have two different dark modes.

Wonder if that's a "feature" rather than a bug? 😉

(not really, it's definitely a bug)

[lucydodo]

Yes, it's not what we intended anyway, so I guess it's a 'bug'. I'll try to check how it works on other operating systems first.

In my case there is a glitch with an element displaying in light theme:

All new tabs are named S... and it also looks like a glitch:

[justinclift]

@rafrafek Does that S... problem still show up if you resize the window to be wider?

I'm still thinking it's a bug though. Am just wondering. 😄

[rafrafek]

Yep, still there after resizing

[justinclift]

k. Sounds like we might need to add some code that manually changes the width of the tab titles to be longer. 😄

I forgot to mention I'm on 3.12.2, so the behavior may be different on the master branch. I'll try to test the master branch tomorrow.

The s... tab name was recently brought up in discussions (#3548)
I don't see this on Windows.

[rafrafek]

Same thing on both 3.12.2 and on the latest build:

The screenshots in @lucydodo's description look good to me. It's working as designed :)
Glitchs reported by @rafrafek are another matter. They should be fixed.
