Bug description

I am sorry for such a stupid bug report, but I cannot find a way to disable the custom window titlebar. Is there a way to make the app use the system default window decorations?

I came here to post the same thing. In Plasma I have no ability to right click on the titlebar to move to a different desktop/activity. Also it just breaks visual consistency.
