Wallpaper does not cover entire screen

[humptydumpty]

@djmaze I uploaded my own wallpaper and made sure it's 1920x1080 (that's what is being used for Snow Dark v1) and tried all the different themes but the wallpaper does not extend all the way like it does with Snow Dark v1. Is this by design or a bug?

reported upstream here: https://github.com/the-djmaze/snappymail/issues/488

P.S. I'm loving the "remove background and text colors from message body" feature. I can finally have true dark mode now.

Fixed by DJMAZE. Thx!

Design was "contain" so that the whole image is shown.
I've changed it to be "cover" to cover the whole screen.
