I’m using desaturation as a way to manage screen addiction and so far I was using grayscale effect from the desktop effects but since maybe around 5.20-ish (not sure about this) it stopped working.
Still works in a wayland session but it’s just too unstable for daily use.
Is there any way to get the desktop effect to work again? I’m open to any other suggestion too.
Welcome to the community! This sounds a bit like the issue reported here, where the solution was apparently to reset Desktop Effects to defaults: Desktop effects have been suspended by another application - #17 by bob418. One user also reverted each change previously made to their Desktop Effects, one by one, and then could not reproduce the issue anymore.
