I've done some testing and I found that the behavior of centering wallpaper is
different depending on if the wallpaper is larger or smaller than the display
resolution.
When using an image smaller than the display resolution, centering the
wallpaper (and other settings) works as expected.
The result is different than "scaled, keep proportions"
When using an image larger than the display resolution, centering the wallpaper
(and other settings) *also* reduces the image size, as reported.
The result is the same as "scaled, keep proportions", as reported.
Configuration:
Laptop in docking station with 2 external monitors
Dell XPS laptop internal screen 2560x1600
LG external screen (DisplayPort) 3440x1440
LG external screen (HDMI) 3440x1440
Tested wallpapers on one 3440x1440 monitor
Test: Image is smaller than the display
Wallpaper size 1920x1080
Settings work as expected
Test: Image is bigger than the display
Wallpaper size 5120x2160
I'm adding an attachment to show how this wallpaper is displayed in Centered
mode on my display.
I added a red border to the wallpaper image to make it easier to see that it's
scaled down. The white borders on the side are because the image has a slightly
more narrow ratio.
I'm adding a second attachment to show the visual difference between the two
resolutions, and the rough area I'd expect to see of the large wallpaper.
