Screen flickering in dual screen setup in 13.1

I have a dell xps13 ultrabook with an intel graphics card, the laptop screen is 1920x1080.

When I connect my extra screen 1680x1050 the top of the screen flickers.

Things I have tried without effect:
- disabling desktop effects
- change Xrender to OpenGL
- lowering the resolution of the screen (still keeps flickering)
- disabling the laptop screen so it is only 1 screen config (still keeps flickering)
- installing xrandr: this crashed my xserver and forced me to reinstall opensuse (not doing that again).

In attachment you will find my Xorg.0.log file for more information:

Before the new install of 13.1, this never occured. Perhaps something with the intel graphics driver?

Is there another log file I can upload for more information?

Thanks for your help.
