cosa intendi? Sia le finestre aperte che Plasma?

ma magari intendi semplicemente che forzi la chiusura con una combinazione da tastiera o simili.

An issue we were not aware of before the release (bug was opened during beta phase, but not confirmed before the release) are freezes when changing any KWin related settings. In fact it is not a freeze. You can still use Alt+Shift+F12 to disable compositing and enable it again and everything works fine. We still do not know what caused the problem, but it seems to be related to enabling direct rendering by default. Unfortunately I am unable to reproduce this problem on the only Intel based hardware I have access to. The only solution so far is to disable direct rendering in general again, but this would be a regression for all users where it is working fine (see above: it cannot be reproduced on each Intel hardware).
