Are you sure this fixes it? I've tested it now with Qt 5.5 and it just completely broke the skip taskbar feature (= plasma popups are shown ALWAYS in taskbar). I was experimenting with various workarounds too, but found none (other than always using Popup as window type for Plasma::Dialog instead of normal window). I think it is because the _NET_WM_STATE hints are reset by Qt before Expose event, not in Show event. But I'm not sure about this one (didn't look in the code). My patch however fixes it correctly :) - David Rosca On March 15, 2016, 2:36 p.m., David Edmundson wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
