After the latest upgrade, the color inversion desktop effect comes with KDE stopped working. Is this a bug or it's just me?
I always invert the color of the screen when I'm reading articles, white background hurts my eyes.
The default activation key for color inversion desktop effect is ctrl+win+i, I can see the effect item in the desktop effect menu, and turned it on and off multiple times, but it's not working anymore.
I tried restart the computer and restart the Plasma, didn't work.
