Summary
A newly appearing server tabulator bar does not respect dark theme setting.

Environment

• Operating System: Linux Mint 19.3, Cinnamon, Dark Theme
• Mattermost Desktop App version: v4.4.0-rc1 (2020-01-30) Build Hash: c81e4f87c20a717b1dc52b2b77780fa789e19148
• Mattermost Server version: X.X.X

Steps to reproduce

1. Choose "Window dark" Theme in settings
2. Open Client Application

Expected behavior
Complete Mattermost UI should adhere its theme or at least it should only appear on using more than one team/server. After reading #844 it seems that the issue itself is already older, but the new behavior of 4.4 to always show the bar exposes it to every user.

Observed behavior
The new title tab bar is in bright theme, even though also the Desktop UX Theme is a dark theme

Maybe similar or related to the much older #844 ?

Same happening on Fedora 31 using Gnome 3.34

Maybe similar or related to the much older #844 ?

That is a different issue actually since the old bar didn't have any support for dark-themes at all.

Hey @bentolor,

Unfortunately choosing the 'Windows Dark' or 'Mattermost Dark' theme in the app is not the setting to turn on dark mode in the desktop app.
You'll have to use the 3-dot menu, go to View > Toggle Dark Mode.

Note we have a ticket open to follow the Windows OS theme option (as we currently do on Mac OS), but it currently blocked on us updating the Electron 7 dependencies: https://mattermost.atlassian.net/browse/MM-22279

Thanks for the pointer, @devinbinnie. This actually does render the top bar in an appropriate dark color. Yes. Quite hidden, though.

@bentolor thanks for reporting, seems like it got solved so I'm closing the issue, feel free to reopen if there is anything else left to handle
