SUMMARY Spotify shows a visible notification every time a new song plays. I find these distracting and want to block them from within Plasma. Clicking the settings icon on one of them yields a blank notification settings window. This doesn't happen for notifications from other apps, like from Discord or NeoChat. STEPS TO REPRODUCE 1. Install and use Spotify 2. Play a song 3. When the "Now playing" notification appears, click the configure icon in the corner of it OBSERVED RESULT The notification settings window will be blank, your only option is to go back. EXPECTED RESULT You should see the normal notification settings, and be able to block the notification if you'd like. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Plasma 6.4.0 on Fedora Linux 42 KDE Plasma Version: 6.4.0 KDE Frameworks Version: 6.15.0 Qt Version: 6.9.1 ADDITIONAL INFORMATION These notifications are distracting to me because, for some reason, they grab partial window focus. Trying to close a window with Alt+F4 while one of them is visible, will close Spotify, stopping my music. Trying to use Alt+Tab to switch to a window I was previously using after one of these notifications pop up causes Spotify to appear, getting in my way. These are likely their own bugs though.
I can confirm that clicking on the notification goes to its settings page, but this page is broken, as it doesn't show the header where you can disable the notifications for this app. But if you go back (or open the Notifications KCM directly), and then Applications > Spotify, the page shows correctly (at least for me) and one can disable them. Checking a bit around, I see this issue happens also with other apps, even KDE ones, like Spectacle, but not with a "Low Battery" one from KDE Connect. Summarizing, if the notification belongs to a registered event, this event is selected and the page is shown correctly. If the notification doesn't belong to a registered event, the KCM moves to the page, but it is a bit broken when it shows. I remember this mechanism being a bit brittle, will take a look soon
Got a hint of what's going on. Apps that don't have a custom .notifyrc config file (such as 3rd party apps using the notification service) actually use a plasma_workspace event. When pressing "configure" over such notification, the kcm receives this as an argument, and gets misleaded: It tries to configure the app from the desktop entry (ex. Spotify), but it opens in "system notifications" mode with no events to configure. For a Spotify notification, the KCM is receiving these arguments: kcm_notifications --desktop-entry com.spotify.Client --notifyrc plasma_workspace --event-id notification Or when clearing the trash in dolphin: kcm_notifications --desktop-entry org.kde.dolphin --notifyrc plasma_workspace --event-id 'Trash: emptied' Not sure yet where to try and fix this issue. In the first case we'd want to open the notification settings for "Spotify", but on the second one I think it's better to actually open the system notifications for the trash event. But we're mixing both and failing to show the right configuration in both cases.

Pushed by iasensio into branch 'master'. kcms/notifications: Fix broken "configure notification" page When clicking the configure button on a notification, we launch the KCM with the notification info so it directly navigates to the specific app/service and event. When the notification event belongs to plasma-workspace we try to show the System Notifications index, but if there is also a desktop entry, the page will override this index to the application's one, showing a "broken" page. Fix this by setting all the desired properties on the call that opens the Sources Settings page, instead of calculating it after the page is loaded.
