Incorrect scaling on ultrawide monitors

[soni801]

The problem
In its current implementation, the default images will scale incorrectly on ultra-wide monitors due to the background-size: cover; in index.css. This causes parts of the image to end up outside the visible screen area.

My suggested solution
This should be fixable by replacing the aforementioned styling with:

background-size: contain;
background-position: center;
background-repeat: no-repeat;
