Why are you using this image of 414k to display at a size that could be managed in about 4K!!!
The image is natively 1920 x 1200 but you are only showing it at about 180 x 112 and could be compressed down to just a few k.
If you are talking about my .test example then you need to make sure the background-size matches the intrinsic ratio of the images. I just used 130x130 for testing but it should not be square it should be the correct aspect.

Although I'm not sure if that's what you meant and I've finished for the day anyway
