Nov 19 19:46:03 hello kwin_wayland[47984]: KPackageStructure of KPluginMetaData(pluginId:"kwin4_effect_grayscale", fileName: "/usr/share/kwin/effects/kwin4_effect_grayscale/metadata.json") does not match requested format "KWin/Effect"

metadata.json
{
  +"KPackageStructure": "KWin/Effect",
  "KPlugin": {

the above can be fixed by adding "KPackageStructure": "KWin/Effect" to metadata.json but then I get this error:

Nov 19 20:06:27 hello kwin_wayland[47984]: kwin_scripting: /usr/share/kwin/effects/kwin4_effect_grayscale/contents/code/main.js:87: error: Cannot call method 'connect' of undefined

the plugin works if I comment out line 87,88 in main.js, dont know if there is any ill effects

 main.js
    effects.windowActivated.connect(grayscaleEffect.windowActivated);
 /*   effects['desktopChanged(int,int)'].connect(grayscaleEffect.desktopChanged);
    effects.desktopPresenceChanged.connect(grayscaleEffect.restartAnimation); */
    effects.windowClosed.connect(grayscaleEffect.cancelAnimation);

This is awesome -- it wasn't working for me under kwin 5.21.4 until I changed my renderer to OpenGL 3, not OpenGL 2.

it is not possible to bind this effect, and this is very important to not open system settings every time I need to disable|enable this function

The effect is working, but only on the main display.
Effect installed from effects catalog.

KDE 5.76.0

Would it be possible to exclude a software from the Grayscale effect.

I would like to have colors in educational software only (Anki and GoldenDict) and leave the rest in Grayscale.

Would it be possible to implement that feature ?

Thanks for your great work !

This version doesn't seem to support KDE6

Here's a working fork for those that are looking: https://github.com/lliurex/kwin-grayscale-effect/tree/master

For example, white becomes light orange, grey becomes dark orange, black stays black- but with any colour the user picks. This would let people create a "sepia" effect, or keep the reduced eyestrain that tools like Redshift give (but with better saturation, closer to the original image), or just pick their favourite colour because it's fun.

As you can see in the attached video, on enabling the grayscale effect and trying to minimize the settings app, it is leaving an afterimage.

On a side note, it is a much needed effect and I really appreciate the work you have done.
