Found an interesting bug in windows 11 with Display Fusion, and wanted to report.
When swapping to a different virtual desktop, the DF background shows, then reverts to the windows background, and after 2-10 seconds back to the DF background.
I will provide whatever will help with this issue, assuming it's not already on the list of known issues.

Apologies, after one of my many reboots in the last few days it's resolved and no longer doing that.

Hi there.

I appear to be experiencing the exact same issue (though 2 years and several releases later).

Whenever I switch beteen virtual desktops (usually, but not always) another default Windows wallpaper shows for a few seconds and then usually switches back to the DF desktop.

I have attached a video of this if this will help you at all.

I am using Windows 11 Pro 22H2

I ham using DF 10.1.1, but this was also happening with 10.0.0.

Thanks
Phil

Thats a shame, but thanks for the response Owen.

Hi I'm really sorry but I'm having an issue related to this after installing DisplayFusion and then uninstalling it and I'm at my wit's end.

Before I installed DF, when I switched Virtual Desktops, Windows would seamlessly transition between different backgrounds.

However, after I installed DF and tried to apply a background, every time I switch virtual desktops, there's a slight flicker as the background unloads to black, then the new background appears in.

The problem is that I uninstalled DF totally but this still happens. I have no idea what settings DF applied that cause this to still happen. I've done several reboots and resets of my background/personalization settings and this still applies. It's really minor but it annoys the heck out of me, especially because this issue didn't exist before I installed DF.

I can post a video if needed. Apologies if this isn't the right thread for this, it just seemed extremely related so I posted here first.

Edit: I've managed to solve this by temporarily turning on Windows Spotlight for my background and then returning it to a picture-based background(??), but after reboot this comes back. I'm guessing Windows Spotlight seizes control of some setting that was updated.

Here it is -- the background basically shouldn't be black at any time, for either background of the two monitors. It didn't do this before I installed DisplayFusion (and I tried resorting to setting Spotlight again but it's failed to fix it this time).

In the video I posted I'm using the hotkey shortcut to switch between virtual desktops, but the exact same thing happens with manually selecting them using the taskbar too.

Yes, but I just noticed the problem also no longer happens if I have it on Fill for the background rather than Span. Though at some point it definitely was breaking for Fill, too... but for your specific question about same image, still gets the same black flicker from an unload then reload first.

Single image. I tested slideshow at a couple points both before and after installing DisplayFusion, though.

Your comment made me think of something else, though: I tested, and it turns out what's happening is that Windows is actually defaulting the Solid Color option while the Picture background is loading. In the video I posted, it's a black screen, but that's just beceause my Solid Color was last set to black. I changed it to another color, and you can see it using that color (bright pink in my example) before the picture loads again. Again, still works on Fill but triggers anytime I have a fit option that requires the image to not cover the entire screen as it moves between virtual desktops.

Again, my original experience is that Windows would never show that solid color, it would just capably go from image to image. So I'm not sure if there's a setting that controls whether Windows decides to render the fallback solid color that's been manipulated.
