I'm not sure what exactly is the cause of this, but I've noticed that I seem to get a lot of composite wallpaper images (all 3 monitor wallpapers combined into one image) saving into my pictures folder. I assume it's display fusion doing it, because it is the one app that is in control of my wallpapers. But it could also be something windows is doing ¯\_(ツ)_/¯.

I noticed it happening on Windows 10, but never got around to troubleshooting until now.

Windows 11 25H2 (26200.6899)
DisplayFusion

Weird, my edit didn't save. I'd like to mention I think it happens when I switch monitor profiles. I can see composites for when I'm in the 2 monitor mode, and 3 monitor mode.

Anyways, here's the debug info attached.

I do have stuff being backed up automatically, but only in protected folders. That does not include appdata. I'd have to maybe use process explorer to see if OneDrive touches anything in the appdata folder when DisplayFusion makes the changes.

Mmm, Site seems to be having issues, since it's taking a long time to post, and double posted.

I digress, I will note that it's not every time the wallpaper changes that it ends up in the pictures folder. I just changed the wallpaper now and didn't see a new one generated. The process monitor logs also don't show anything wonky, but I suspect I'd have to catch the bug in the act as it occurs.

I have DisplayFusion setup to rotate wallpapers once an hour I believe, so not sure how often it sees the bug.
