MacBook Air M1 wallpaper orientation changed after update

Hi, I just upgraded my MacBook Air M1 to Tahoe 25.3 and it changed the orientation of my wallpaper and it seems like any picture that I use that is in a similar mode gets changed...... IT didn't happen in the previous version....


Here's the picture in photos .....



and here's what it looks like on the desktop .....


I've just about tried all settings, but it stays like this

Bug or feature ?

That HEIC iPhone (portrait) image is 3024 × 4032

Your MacBook Air Display is (diagonal) 2560-by-1600

In simple terms, the image is tall and your Mac's display is wide.


If it is Imported into your Photos App, check to see if it is in the proper orientation....

If it is sidewise in the Photos App, rotate it and try selecting that rotated image.


Then if it is showing on your desktop wallpaper with blank spaces on each side..

You need to crop out a wider portion of the image to use as wallpaper.
