When autostarting or when restoring a previous session, the Kontact window opens with an offset for the first time. After minimizing Kontact to tray, the next time the window opens correctly.
STEPS TO REPRODUCE
1. Add Kontact to autorun with --iconify parameter
2. Reboot the system
3. Open Kontact in full screen
The Kontact window will open with a shift down, see screenshot.
The Kontact window should open correctly.

I was told that this problem occurs because the application starts up faster than the panel.
