When you set your Task manager to highlight window on hover and then middle click to close that window it will get stuck with all windows transparent until you hover your mouse once more. So using hover to highlight and middle to close is pain. The same behavior on 5.8.5-5.9.1. Easiest way to test it is to middle click (close) last window on task list. It would be nice to fix this :)
This will be fixed soon by https://phabricator.kde.org/D4525
Git commit dc17f78ebcc76600040a8d2ef8c57b9a41a8d06e by Eike Hein. Committed on 13/02/2017 at 10:42. Pushed by hein into branch 'Plasma/5.9'. Fix crash when invoking Present Windows with the group dialog open. Summary: This fixes a regression from aeec4ae8 which unsets the taskManagerItem prop when the group dialog is shown to intentionally break window highlighting while the dialog is open. This patch instead fixes highlighting from the group dialog properly by including it in the highlight list. Also adds some extra crash guards.
