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.
