What is "animated hue"? A 3rd-party wallpaper plugin?

animated hue - background

I am not aware that this the third party plugin. It always comes with KDE / Plasma.
Comment 3 Nate Graham 2022-07-13 21:09:06 UTC 
That's a 3rd-party plugin, yeah. I guess your distro ships it by default, or you installed it a long time ago and forgot about it. Does it work when used as a desktop wallpaper?
Comment 4 Daniel Duris 2022-07-14 08:05:32 UTC 
I see. Yes, it works for the wallpaper.
Comment 5 Nate Graham 2022-07-14 15:08:15 UTC 
Ok, so the plugin isn't completely broken.

Can you set it as your lock screen background and then run the screen locker in testing mode?

First open a Terminal window and run `find /usr -name kscreenlocker_greet` to find the full path to kscreenlocker_greet (it differs by system). Once you've found it, run it with the `--testing` argument. Then paste the terminal output into here as a new comment. Thanks!

I checked the path, there is no such image as there is no such path (./SafeLanding/contents/images/5120x2880.jpg)...
Comment 7 Nate Graham 2022-07-15 20:48:44 UTC 
As I suspected, this is an error in the 3rd-party wallpaper plugin. That path no longer exists because Safe Landing was moved to being the default wallpaper in Plasma 5.25, so now it lives at:
/usr/share/wallpapers/Next/contents/images/5120x2880.jpg

In Plasma 5.26, it will go back to living at
/usr/share/wallpapers/SafeLanding/contents/images/5120x2880.jpg

Since clearly this path is volatile, it's not appropriate to use as as hardcoded value. I would recommend that you report the issue to the developer at https://github.com/Zren/plasma-wallpapers/issues

Thank you for your patience and help! I am going to report it.

You're welcome!
