Toni,
Symptom: Fullscreen D3D11 720x576 resolution has correct Aspect-Ratio, Fullscreen D3D11 1024x768 resolution image is stretched.
I did a comparison between the two. Log entries when going Fullscreen with 720x576:

The only difference that I spot is with "D3D11 Highest freq":
Code:
720x576: 148351648/2475000=59.00
1024x768: 78750000/1049600=75.00
Going Fullscreen with D3D9 gives minimal output (Aspect Ratio is correct though):

Could this very well just be a display driver bug?
