I just spent a half hour googling around for a fix - all my Konsole (KDE/opensuse 13.1x64) windows have no "decorations" (meaning I can't resize them with click and drag). I also don't have access to the menu item which enables/disables this, because that part of the window is part of the decoration (right click > More Actions > Special xxxx Settings). Can anyone help me with a mouse sequence to turn them back on? thanks!

PS: The term "decorations" is somewhat ambiguous in KDE - fairly often it refers to interaction with Desktop Effects.
