Hello dear KDE Community,

I just recently stared using Kubuntu and I have been fiddling around to get my triple monitor setup working. Everything seems to run fine now, except for one thing:
Whenever I click "Maximize" on a window title bar, the window will maximize over all three screens.

The behavior I'd like to see is that the window maximizes only to the currently active screen (or to the screen the most % of the window is in (or however its determined where to maximize it when it is between 2 screens)).

I tried Enlightenment as window manager just to rule out that its not my nvidia x server settings; here it maximizes just like I want it to.
Don't really know what to look for; didn't find a setting neither in the graphical settings of KWin nor in the the config files.
I'm sure someone here can point me in the right direction. Any kind of help is greatly appreciated.

Kind regards


Some details:
Kubuntu 16.04.1 LTS
2 x Nvidia GeForce GT 730 (no SLI Bridge) // Driver Version 375.26 (latest stable)

Hi, I am in the same situation.

I found it didn't matter which distro is used (and I've been through a few testing this). The common element is that they all ran Plasma 5.

2 x Nvidia GeForce 9800 GT (no SLI Bridge) // Driver Version 340.101

Is there a way to get the same maximise action as Plasma 4?

Thank you.
