Extra background on (New) Card visual that cannot be removed

While I was carefully checking all the menus to look into this padding issue, I noticed that I hadn’t checked one particular menu: “Multiple cards layout”… and indeed, there was a background option in there that was enabled..!

About what I said regarding the themes.. this was a red herring… they were only activating this background setting for multiple cards, which also affected my single card…. I must have gotten a bit lost among all these scattered options, which all seem to do almost the same thing… almost.

Thank you very much for your help, it really made me take a closer look!
