Spectacle doesn't send anymore a notification to Plasma. It is very annoying because that interrupts the workflow Capture->notification->drag&drop
Please let us know your version of Plasma and Spectacle, as well as what exact steps you followed to capture your screenshot. Also, make sure that you have not turned off notifications for the "Screenshot Capture Utility" in Systemsettings → Notifications.
Spectacle: 18.04.0 Plasma: 5.12.5 KDE Frameworks 5.45.0 Qt 5.10.1 Windows Sytem: xcb Steps: open spectacle, capture a screenshot (whatever: full screen, region, etc) Notification is setted
Thanks, I see. There was never any notification for when you triggered the snapshot from the dialog. The notification will only appear in case you use one of the global shortcuts, i.e. to capture a screenshot without using the dialog at all. This was always the case and has not changed recently. As for drag-and-drop, you should be able to grab the image displayed in Spectacle's dialog.
Sorry, I miss a step: there was a notification after saving. I reinstalled Spectacle 17.12.3 and it works.
Ok I understand: the notification works only if i check "close after saving". It makes sense. Thank you!
