Linux Desktop app — Start on login starts app as a blank window
Found on Desktop app v4.5.1-rc3 on Linux (Ubuntu 18.04)
1 - Navigate to settings/preferences: Windows: File ➜ Settings (CTRL+,)
2 - Enable “Show icon in the notification area” (menu bar at the top on Linux)
3 - Restart the Desktop app to allow that setting to take effect
4 - Return to settings and select "Start app on login"
5 - Exit the Desktop app ➜ CTRL+Q
6 - Restart your machine
Expected: Desktop app starts but is minimized and when you click on it it opens and is usable
Observed: Opens in the foreground instead of being minimized, and the window is blank
4.5.0 starts minimized, and when you bring it to the foreground everything is loaded as expected
If “Show icon in the notification area” is not enabled then the app starts minimized as expected
You are able to bring life to the blank window if you do the following
Right-click the Mattermost icon and go to All Windows and click on the window shown (also blank)
Note: The Mattermost app doesn’t show as running at the top until you do the above step
Right-click again, select New Window and wait a few seconds (video attached)
QA Test Steps
It's all good. I removed the Desktop app and reinstalled fresh (I use terminal and the .deb file) and it worked as expected with v4.5.2-rc1.
I tested again the .deb one on 18.04 and couldn’t repro the problem: app started in the tray without showing any blank page, clicking on the tray icon showed a loading screen but that is related to my currently limited connection (really bad). which kind of installer did you use?
Tests using v4.5.2-rc1 worked as expected on Ubuntu 20.04 but continue to fail on Ubuntu 18.04.
ubuntu 20.04 doesn’t display this problem, I’ll try to reinstall 18.04 to see if I can replicate
