SUMMARY

When window A is focused in current desktop and new window B is created in other  desktop, desktop doesn't automatically switch to where the new window has been opened.

STEPS TO REPRODUCE

You have at least two virtual desktop. One is Desktop A, the other is Desktop B.

You have any two different applications, for example: Dolphin, Juk.

1. Open Dolphin and Juk in Desktop A.
2. Set KWin rules so that Juk is forced to show in Desktop B. Juk will be switched to Desktop B immediately.
3. Switch to Desktop B.
4. Minimize Juk in system tray (click close button) or simply quit it.
5. Switch to Desktop A.
6. Click on the title bar of Dolphin so it is focused. (Skip this step will cause totally different result)
7. Click Juk system tray icon or from application launcher (Kick-off).

Can be reproduced with any applications.

OBSERVED RESULT

You are still in Desktop A but Juk is opened in Desktop B. You have to manually switch to Desktop B.

EXPECTED RESULT

Juk is opened in Desktop B and you will automatically switch to B, too. So you can see the new opened Juk window immediately.

ADDITIONAL INFORMATION

Comment 1 Martin Flöser 2018-11-16 12:32:29 UTC

The described behavior is not a bug but expected behavior. Juk is stealing focus by just opening a window (minimize to systray is like opening a new window). KWin correctly refuses to switch the desktop for a focus stealing window. The bug is with Juk for not providing enough context hints for KWin to notice that it's not stealing focus.

It is not only for system tray applications. For example, you open any new applications which is opened in another desktop, it won't be switched to the desktop. Is this also an expected behavior?
