When setting the background image in General -> Window, the background image does not show behind the canvas after a restart, unless I'm misunderstanding what it's supposed to do. I've tried multiple images, png and jpg, locally and mounted, ext4 and ntfs and no luck. 5.2.0-prealpha (git ff161e4) (Appimage)
This option is only relevant for "Multiple Document Mode" set to "Subwindows", if set to Tabs it will do nothing. When in subwindows the background space in which the subwindows float is set to the image you select. This has no effect on the border around the canvas of the image
In that case, shouldn't the option be disabled or hidden when Tab mode is selected then?
A possibly relevant merge request was started @ https://invent.kde.org/graphics/krita/-/merge_requests/1620
