I use Kubuntu 14.10 Plasma 4 and it seems to use some sort of Adaptive Activation area menu, i.e. it eliminates corner steering by default. This affects all applications I have tried (kickoff start menu, Eclipse, Google Chrome) so it seems to be a system setting.

Is there anyway to disable Adaptive activation areas in the menu to allow corner steering?
