Description Mustafa Muhammad 2016-02-22 19:00:53 UTC 
I am testing wayland session, and after I type in the search box, I go to firefox and can't type there (the letters I press are being written to the menu search even if it is closed, then plasmashell crashed.

Reproducible: Sometimes

Comment 3 Marco Martin 2016-02-24 13:26:50 UTC 
kinda expected, needs wayland-specific libtaskmanager to be implemented
Comment 4 Eike Hein 2016-06-16 23:20:51 UTC 
The new Task Manager backend shipping with Plasma 5.7 has proper Wayland support.
