Created attachment 871743 [details] screenshot showing the notification popup from TB Since a few months I see a strange behaviour in the Plasma GUI: - visual popups from the Thunderbird calendar are displayed on top of all other windows - they do not disappear even when the TB window is no longer the active widget See screenshot: here Thunderbird is behind Firefox and Firefox is the active window. The black popup from the TB calendar is still visible on top and does not disappear even when the mouse is used on the FF window I have no idea if this is a bug of Thunderbird, the GTK framework or something strange in QT/the Plasma GUI (kwin?).
