Interacting with KDE desktop elements or changing wallpaper settings on high refresh rate monitors causes shader to speed up.

[Fighterbuilder]

When using this wallpaper on a monitor with a refresh rate above 60 Hz, interacting with desktop components of KDE Plasma 5 (not including applications like Dolphin) causes the shader to speed up very briefly, and it's very distracting. https://github.com/y4my4my4m/kde-shader-wallpaper/assets/33814663/a34f79b9-2235-44fe-b5bf-1e5e37e5e7c9 In this case, I'm currently using a monitor with a refresh rate of 240 Hz but the problem is still visible in a 60 FPS recording.

A similar issue occurs when opening the wallpaper settings to adjust the shader, this time speeding up consistently for the entire time the menu is open. https://github.com/y4my4my4m/kde-shader-wallpaper/assets/33814663/6f8d570a-74e1-45c9-8400-90b1099e8a0c

Changing the refresh rate to 60 Hz does resolve this problem, but I would rather not have to do that.

Oh wow that's super strange.

Thanks for sharing. I have a 120hz monitor, however so far I've only been working from a VM so I hadn't noticed this.

I'll see what I can do

What if you try changing 16 to 4 here:

https://github.com/y4my4my4m/kde-shader-wallpaper/blob/0db87022d8578a2e21e3cc5626d6487a0a899d21/package/contents/ui/main.qml#L194

And 0.016 to 0.004 here:

https://github.com/y4my4my4m/kde-shader-wallpaper/blob/0db87022d8578a2e21e3cc5626d6487a0a899d21/package/contents/ui/main.qml#L214

Does this make sense? I know nothing about shaders

Edit: Actually it should be 4 and not 8 (1/240)

Good thinking. @Fighterbuilder if this works, I'll implement a way to detect the frequency of the monitor and divide accordingly.

Could you please test it?

I'm sorry, I don't really know how to find those files on my install. I'm still very much a Linux noob lol

If you could help point me in the right direction, I'd greatly appreciate it!

It's in ~/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/contents/ui/main.qml the lines you have to modify are by the end of the file inside the Timer {} block.

@Fighterbuilder

In a folder of your choice:

1. clone the project with git: git clone https://github.com/y4my4my4m/kde-shader-wallpaper.git
2. go in the folder:cd kde-shader-wallpaper
3. switch to the plasma6 branch: git checkout plasma6 && git pull
4. modify the lines he's mentioned in the comment above
5. delete the old installation of the plugin: rm -rf ~/.local/share/plasma/wallpapers/online.knowmad.shaderwallpaper/
6. still from within kde-shader-wallpaper, install the modified one from source: kpackagetool6 -t Plasma/Wallpaper -i package
7. restart plasmashell pkill plasmashell && plasmashell
8. reselect "shaders" plugin from your desktop > configure desktop and wallpaper
9. verify

Alright, I'm finally getting around to this, sorry for the wait there. Anyway, I'm on Plasma 5.27.8 - do you still want me to use the Plasma 6 branch @y4my4my4m?
