Bug ID: 513733
Summary: Regression: applications cannot minimize themselves to
system tray
Classification: Plasma
Product: kwin
Version First 6.5.4
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
SUMMARY
There are some applications that provide a "minimize to system tray"
functionality where "closing" the application window (by the Ⓧ in the title
bar) should actually only close the application window and let the application
running in the background maintaining its icon in the task bar. An example of
this is the spotify application.
Until recently, this used to work. After an upgrade to plasma 6.5 it does not
anymore. The Ⓧ button has simply become a NO OP and trying to close from the
task manager is the same.
Note that the Ⓧ has no visible outcome on plasma, but the applications
themselves get to think that the main window is closed. The spotify client is
an excellent example of this because the systray icon notifies the window
state. When spotify thinks its main window is open the systray icon provides an
option to "Minimize to tray" and when spotify thinks its main window is close
the systray icon provides the option to "Show Spotify".
Not 100% sure this is really a regression even if it looks very much like one.
It may be the case that the application has merely moved to operate as a
wayland application and it would not be a surprise if — as we are now used to —
wayland breaks useful behaviors by policy (e.g. wayland developers knowing
better that applications should not ever be able to close their main window
because).
In any case, this used to be a quite useful behavior to avoid polluting the
taskbar, so please try to see if it can be restored either fixing a regression
or working around wayland limitations. Hopefully it would be great if this
could be fixed before after two more years the wayland developers accept that
applications closing their main window and leaving only the systray icon is not
an extra dangerous behavior but something that can be accepted in the protocol
;-)
STEPS TO REPRODUCE
Spotify is the easiest reproduction case.
1. Install the official spotify client
2. Start it
3. Go to settings and activate "close button should minimize the spotify window
[to system tray]" in the "Startup and window behavior" section
4. Try to close the application
OBSERVED RESULT
The application window does not close, but the systray icon gets to think that
the application main window is closed (now it says "show spotify" rather than
"minimize to system tray").
EXPECTED RESULT
The application should work as intended by letting its main window be closed
leaving the app running in the background with an indication of that in the
systray.
