tested it more, and this is normal, even with the old way. I don't think there is much that can be done in general, because when the applet changes containment, its appletappearance (and its mouseeventlistener used to drag ght thing around) gets deleted, and the applet reparented to a new one. I tried to see what would be needed to recycle the same appletappearance, but the codepath is going trough Containment::addApplet, i would like to keep it that way REPOSITORY R119 Plasma Desktop REVISION DETAIL https://phabricator.kde.org/D4969 To: mart, #plasma Cc: davidedmundson, plasma-devel, progwolff, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol
