Description Alexander Potashev 2019-01-05 19:44:11 UTC 
SUMMARY
[Wayland] Launch feedback on taskbar does not work.

STEPS TO REPRODUCE
1. Run wayland plasma session.
2. Click on the Google Chrome icon in taskbar's quick launch area.
3. Look at the taskbar.

OBSERVED RESULT
Nothing happens until the Chrome window is finally visible.

EXPECTED RESULT
Taskbar should display a fake button for Chrome immediately to indicate that my click on the Chrome icon is acknowledged by Plasma.

Windows: 
MacOS:

ADDITIONAL INFORMATION
Comment 1 Eike Hein 2019-01-06 10:00:30 UTC 
This is known errata - we don't have support for launch feedback on Wayland yet.

also no bouncing cursor even with Qt 5.14.
Comment 4 boingo-00 2020-09-08 18:27:40 UTC 
Is it technically possible to fix launch response?
Comment 5 Nate Graham 2020-09-08 19:50:19 UTC 
yes. :)

Comment 11 Nate Graham 2021-05-05 16:13:31 UTC 
Since the Wayland protocol has been merged, this isn't blocked by anything upstream anymore and we can implement support on our side. Re-opening the bug report to track that.

Comment 13 Alexey Ilyin 2021-07-16 11:38:22 UTC 
As far as I understand the spec of the new xdg-activation protocol, the activation token transfer should be completed by the application being activated.  Thus, changes are required in all applications for the activation mechanism to work correctly.  And if KDE applications can still be patched, it's not clear what to do with third-party applications.

My suggestion is that regardless of the implementation of the classic launch feedback (bouncing cursor, etc.), it makes sense to add visual feedback at least on the taskbar itself.

There is currently no application launch feedback on Wayland, which is inconvenient when the application takes a relatively long time to launch.

I'll try to suggest a sequence of actions when invoking the application from the taskbar:
1. User clicks on the launcher icon of application A;
2. The taskbar draws a visual feedback on this icon, as it does on X11;
3. At the same moment, we start a timer with the time specified in the General behavior KCM;
4. When the corresponding application starts, the taskbar knows about it (by matching the launched application to its .desktop file), and we just stop the timer immediately;
5. If the newly opened application window does not match the user-invoked icon (.desktop file), we do nothing;
6. When the timer expires, we stop displaying launch feedback, considering that the application has not started, or it does not correspond to the called .desktop file.

And yes, I understand that if this is done, users may start submitting bugs like this (https://bugs.kde.org/show_bug.cgi?id=162321), but it seems to me that this is not as scary as the lack of feedback at all.

Thanks for attention :)

On git master right now, I get launch feedback on taskbar on all apps (KDE and non-KDE). Closing as fixed.
Comment 16 Pawel 2021-07-22 17:36:45 UTC 
doesn't work when launching apps from the new kicker app. is there a separate bug for that?

Yeah, see bug 405624
Comment 18 Patrick Silva 2021-07-23 13:21:39 UTC 
I see no feedback in the task managers (tested icon-only and classic modes)
on my fully updated neon unstable.

The only feedback on launch is bouncing cursor. But even bouncing cursor
does not work when I open an external link with internet browser or an app
via kickoff.

Comment 19 Nate Graham 2021-08-03 21:41:25 UTC 
Indeed, seems to be still broken.
Comment 20 Nate Graham 2021-08-20 01:09:40 UTC 
Still in progrss.
