Could you provide any more details on how it isn’t working (like… is the effect messing up? slows and fails to load image?). Take a look at these reports as this might be related to one or both of these bugs:
https://bugs.kde.org/show_bug.cgi?id=483480

https://bugs.kde.org/show_bug.cgi?id=490906
Both talk about issues using high quality images.

[yash]

I went through it earlier, I also used less than 500kb images but images fail to load and black background is shown

[elite]

I say try jpeg keep the name short. I just give it a number. I’ve had luck up to 5120x2880.

This is the image i got it working with.

[yash]

Not working @elite
I tried doing so with name 1.jpeg of res about 2000 and size under 500kb still black bg

[elite]

might be best to change the image your using ive found its super picky. I had it work up to 8MiB files but not all work. Even if they are jpegs.

Is kimageformats installed? I recently discovered that this package was not in the recent package list. My machine that was upgraded from KDE 5 to KDE 6 did not have it either:

Cannot set AVIF as wallpaper

for some reason kimageformats was not installed on my machine that was converted from KDE5 (only had the KDE 5 variant). Once I installed it, I could see AVIF thumbnails and set them as wallpapers. I just checked the recent package list of https://iso.builds.garudalinux.org/iso/garuda/dr460nized-gaming/240428/garuda-dr460nized-gaming-linux-zen-240428.pkgs.txt and only kimageformats5 was listed in the package list Since it is not listed in new package listings, I would make sure you…

I checked it but I recently found out this is the issue of Wayland sessions, after so many time, I switched to Xorg session to check and found it is working properly in X session, hdr, jpeg working atleast, but in Wayland it is not working somehow

Any suggestions to make it work on Wayland?

@yash

Any suggestions to make it work on Wayland?

There are a few issues open reguarding image use that are still open like this one Custom skybox is weird · Issue #7 · zzag/kwin-effects-cube · GitHub
Although I haven’t seen something that is like the issue you are reporting with it being specifically a Wayland session issue.

If the issue only happens in Wayland as you say, I would open up an issue there and be as detailed as you can in the report with the images you are trying to use. Maybe the developer or other users can help pin down what exactly is causing the issues in a Wayland session and eventually fix it.
