background is 100% black after start atom

[FoxOdd]

Hello,

When I start atom, the background is 100% black instead of my custom background.

So I have to go to the panel editor-background.
To solve the problem I tried to check and uncheck the "Custom overlay color" button. After applying, I have my custom background.
But I have to do this every time I start Atom…

Here's an extract from ~/.atom/config.json :

"editor-background":
    image:
      backgroundSize: "manual"
      manualBackgroundSize: "27%"
      opacity: 25
      overlayColor: "#000000"
      style: "background:radial-gradient(rgba(0,0,0,0) 100%,rgba(0,0,0,0.75));"
      url: "/path/to/.atom/pictures/XANAcle.png"
    other: {}
    text:
      blur: 0
      expand: 0
      opacity: 0

I have atom 1.40.1, on Ubuntu 18.04 (and some packages like night-day-theming, ide-python…)
Thanks
