Greetings All,

So I've been a Mac user on and off for YEARS, but ever since returning to the platform with my M4 iMac, I have noticed an odd issue when it comes to changing my wallpaper. I'll try and lay it out as best I can to see if there is an answer for this or there's nothing I can do.

So, in settings, my resolution is set to:

2240x1260. Am I to assume this is only for UI scaling? Because if I take a Desktop Screenshot, the info I am giving shows something different:

The reason I ask about this, is because when I want to choose one of Apples provided/listed wallpapers, the scaling is WAY off, and there is no way to adjust it. For example, I would love to use the one shown, named "Scottish Coast":

Regardless of selected Resolutions or what have you, clicking on that particular wallpaper gives me this:

I cannot adjust it, center, tile, fit, or fill screen. This is always the outcome. I love Lighthouses, and I want to see it. But this is one example. ANY of the wallpapers listed in the settings application do this. The scaling is way off and there is no way to adjust it. Increasing the "resolution" shown in the first image just scales the UI, and the wallpapers are not affected.

Is this a persistent bug? Or is there a fix for it? I've been meaning to ask SOMEONE about this since purchasing this iMac last August. It finally annoyed me enough the other evening to push me to posting.
 
Same thing here. On Sequoia. I checked acouple of others: Scottish lake, Scottish castle, and they scale fine, so I guess this particular one is not properly done.

I don't usually use these.
 
I just tested a few others listed in the Landscape category, and some scale properly and are accurate of the preview, and some do not.

It's odd, many of them have animated previews but are not animated on the Desktop. Should they be? Is this something macOS is capable of?
 
No they don't animate when they're just desktop backgrounds, you can set them to seamlessly turn into animated image when screensaver kicks in. Kinda the idea with these.

The ones not scaling is just flawed QC.

You can test the desktop image turning into animated screensaver by setting one of your display corners to activate screensaver. Do this in system settings, 'desktop and dock', 'active corners' at the bottom of the panel. Move the pointer to the corner to activate screensaver.

That worked!
 
The video used starts off really close to the cliffs, leading to what you see in the first image example I posted. Enabling it as a screensaver as you suggested while also set as a desktop wallpaper allows the video to play through. When you end the screensaver, it slows down and pauses at a point in the video.

I chose to pause it just as it went beyond the lighthouse.

Still a bizarre issue though if you ask me. Just give me a picture of the god damn lighthouse Apple.
