Previews are not updated when using with dynamic wallpaper

[AlpSha]

I'm using dynamic wallpapers that change by the time of the day. But the workspace preview keeps showing the wallpaper that is active when I first login. For example, currently there is sunlight but the previews still show the night wallpaper. It would be great if you could solve this.

Many thanks.

Is dynamic wallpapers a separate extension?

[AlpSha]

It is set by the tweaks tool. Using xml files.

Here is an example xml file for dynamic wallpapers.

This is the first time I've heard of this feature but it seems to be GNOME built-in. Maybe there is an event to which this extension can subscribe to update the thumbnails whenever the wallpaper changes. Everyone feel free to start working on this.

I never thought about the dynamic wallpaper feature, maybe the caching part is actually affecting this.

@AlpSha a little bit complicated to test the dynamic wallpaper for me, I tried to change the wallpaper though and the extension rendered the new one in the switcher correctly. I am afraid that this might be an upstream issue, can you disable the extension and let us know whether you can see the dynamic wallpaper changing in the overview or not?

[AlpSha]

@ebeem Dynamic Wallpapers not updating on Zorin OS's default overview either. I disabled this extension and tried it. It is the same result. It seems that this is nothing to do with you. Sorry guys.

By the way, I found that issue on web. It seems it's fixed on newer versions of Gnome. https://gitlab.gnome.org/GNOME/mutter/-/issues/1597

I hope it gets fixed soon, thanks for updating us about this issue.
