Hello,

I am experiencing a persistent issue where a "ghost" window (displaying a large MS Paint icon) appears on every new Virtual Desktop in the Windows 11 Task View (Win + Tab).

Here are the details of the behavior:
1. When I create a new Virtual Desktop, a window displaying the Paint app icon appears in the Task View thumbnail.
2. This "window" cannot be interacted with normally and appears to be a visual artifact or a background process that DisplayFusion is holding onto.
3. Initially, this was the "Microsoft Photos" app icon. After I uninstalled the Photos app to troubleshoot, the artifact immediately switched to the "MS Paint" app icon.

**Troubleshooting attempted:**
I have confirmed that **DisplayFusion is the cause**. If I exit DisplayFusion, the issue disappears immediately. However, I cannot pinpoint the specific setting causing this, as I use the exact same DisplayFusion settings on another PC without any issues.

I have already tried the following steps, but the issue persists:
* Disabled "Apply transition effects when changing wallpaper".
* Disabled "Automatically fix wallpaper images...".
* Cleared the Wallpaper Source list and re-added local images.
* Manually deleted the cache in `%LocalAppData%\DisplayFusion\Wallpaper_Cache`.
* Reset/Removed Wallpaper Profiles.

It seems like DisplayFusion is creating a background window for wallpaper rendering that Windows 11 incorrectly identifies as an active app window (Photos/Paint) on Virtual Desktops.

**System Information:**
* OS: Windows 11
* DisplayFusion Version: Pro 11.1.1 (Steam)

I have attached screenshots of the Task View showing the ghost windows and my current wallpaper settings.

Could you please advise on how to fix this?

Thank you.

Resolved.
The cause was that images in “AppData\Local\DisplayFusion\Web Images” were not previewed in Explorer.
Disabling “Always show icons, never thumbnails” in Explorer settings resolves this.
