If the resolution of a wallpaper image exceeds the display's resolution, the wallpaper image should be cropped from the center instead of scaled to fit the display. Reproducible: Always Steps to Reproduce: 1. Set wallpaper to an image that is bigger than the display resolution. 2. Set positioning to 'Centered'. 3. Apply. Actual Results: Wallpaper is scaled to fit the desktop without cropping. The background color fills in the empty space. Expected Results: Wallpaper should be centered on the desktop without scaling. Any side that exceeds the display should be clipped while the empty space is filled with the background color. The current behavior is redundant since setting positioning to 'Scaled, Keep Proportions' gives the same results. The new behavior would also match GNOME Shell and MS Windows 'Centered' wallpaper settings.
>The current behavior is redundant since setting positioning to 'Scaled, Keep Proportions' gives the same results. That's only half true. It's the same if and only if the image is larger than the screen resolution.
Oops, thought that was implicit from steps to reproduce.
Bug confirmed (and reproducible) using the latest plasma-desktop 5.6.4.
Center positioning of bigger wallpaper looks ok Plasma: 5.11.5 Apps: 17.12.1 Frameworks: 5.42.0 Qt: 5.10.0 Kernel: 4.14.16-1-MANJARO
Please submit the bug to upstream Qt, because QQuickImage doesn't support "Centered and cropped".
