clone this repository or download the latest release
install from folder: kpackagetool5 -t Plasma/Wallpaper -i kde-shader-wallpaper
install from archive: kpackagetool5 -t Plasma/Wallpaper -i online.knowmad.shaderwallpaper-2.0.1-alpha.tar.gz

You can uninstall it via KDE's desktop settings otherwise, you can uninstall like this: kpackagetool5 -t Plasma/Wallpaper --remove online.knowmad.shaderwallpaper

I'll probably maintain it on Github principally for issues/PR but I'll try my best to maintain both, if anything contact me on twitter @y4my4my4m.

[x] Version 1.0 - Simply load shaders
[x] Version 1.1 - File Dialog added
[x] Version 1.2 - iGPU fix
[x] Version 1.3 - 70 new shaders + autolisting
[x] Version 2.0a - Customize shaders via GUI, directly load shaders from shadertoy.com or file (current version)
[x] Version 2.0.1a - Breaking bug fix regarding the pause/fullscreen feature(current version)
[ ] Version 2.x - Save/Load edits, better customization, better buffers/channel

GUI Customization is highly experimental, bugs will occur.
Shadertoy.com imports doesn't work on all shaders, that is because iChannels/Buffers are not fully implemented yet
Performance may vary depending of your specs, but it's actually not all that resource intensive, depends on the shader too.
If you modify the shader files and want to see the changes, the KDE Wallpaper QtQuick App itself needs to be restart, I recommend simply to pkill plasmashell and restart it.
