            Bug ID: 314790
           Summary: KDE Task switcher does not appear on correct Dual
                    Monitor screen, ignores the cursor on the monitor as
                    the active screen.
    Classification: Unclassified
           Product: kde
           Version: 4.9
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: nwenclaff at gmail.com

When I press Alt+Tab I 80% of the time will not get anythig, the other 15% the
task switcher shows up on the wrong screen (I have dual monitors with Xorg.conf
using Seperate X  Screen Layout not twinview as it does not play nice with full
screen flash videos (shows up on 2nd monitor and not hte primary)), and the
remainder of the 5 % the window switcher shows up on the correct "primary"
screen.

Below is my /etc/X11/xorg.conf

Reproducible: Always

Steps to Reproduce:
1. Install Arch Linux from scratch so it is brand new nothing is modified
2. Install KDE and activate it via systemctl enable kdm.service; login
3. Configure Seperate X Screen via Nvidia-Settings
4. Press Alt + Tab 
Actual Results:  
Task Switcher occasionally shows up, if at all on the wrong screen...doesn't
even take into account which monitor the cursor is on.

Expected Results:  
Task switcher to show up on the active screen in question.
