`hideOnStart` is not working

I confirm (by marking “x” in the [ ] below: [x]):

• This is not a troubleshooting question. Troubleshooting questions go here: https://docs.mattermost.com/install/troubleshooting.html.
• This doesn’t reproduce on web browsers (such as in Chrome). If it does, issue reports go to the Mattermost Server repository.
• I have read contributing guidelines.

Summary Hide on start options was reintroduced in client by #1919. But it doesn’t work as expected, because it does nothing.

Environment

• Operating System: linux.
• Mattermost Desktop App version: 5.1.0 also master.
• Mattermost Server version: 6.5.0.

Steps to reproduce

1. Start desktop client;
2. open settings;
3. check hide on start;
4. terminate client;
5. open client once more.

For master branch

1. npm ci;
2. npm run watch;
3. open settings;
4. check hide on start;
5. make client restart.

Expected behavior Client window should not show at all at start.

Observed behavior Client window stays up even if hide on start option is checked.

Possible fixes

• Previously this handled by show and then instant hide. So it can look like.

• Prevent show() if window is not yet ready.

• Find out why showMainWindow() was called during startup sequence. Concretely this problem is caused by https://github.com/mattermost/desktop/blob/2e740d60bd55c409e756166ff414696d6449fa8e/src/main/app/config.ts#L36

It is, but you need to have libappindicator running on your system, which will give you a ‘Windows-like’ system tray. Some other distributions have a ‘Mac-like’ dock that should also work the same way.
