Hello, I updated to macOS 26.2 and am experiencing serious issues with wallpapers: first of all, they are displayed in low resolution, and the problem worsens if you use a non-native resolution or an external monitor.
In addition, all my aerial wallpapers have disappeared, both downloaded and undownloaded.
I don't know how to solve
MacBook Pro 16″, macOS 26.2
Edit: to fix the issue with aerial wallpaper I deleted the entire folder and rebooted:
~/Library/Application\ Support/com.apple.wallpaper

Already done!
For dynamic backgrounds, I solved the problem by deleting the plist files so that they were regenerated, but the low resolution remains.
macOS 26.2: wallpaper are now Low-res and missing aerial wallpapers
