Background image is not stretched correctly in color section

Hi Kreisi Team,

using the color section of the Layout Editor and editing a background image I would like to show it as full width background image.
Therefor I selected “strecken um anzupassen”. Now the Image isn’t showing clearly in frontend, the image has a 1500px width though.

Am I doing something wrong or should I use something else for an background image as a section?

I tried to find the solution in the forum – but without success.

Thanks for your help.
