After an update I noticed discover was this weird yellow color, I opened settings and noticed it too was yellow, thinking it was some bug, I restarted PC, now everything is yellow. I tried inverting colors but that is something completely different. I'm not even sure what was updated to cause this.
My background isn't yellow, it's mountains with a blue sky.
I believe this might be an issue with an app called redshift that automatically comes with mint, it uses geoclue2 which relies on Mozilla Location Service which got shut down like 2 weeks ago. Maybe it malfunctioned that even uninstalling it doesn't help
Never used redshift only to see what the heck it was.
I will be honest I didn't know much about kde as only had experience with gnome and cinnamon, when plasma 6 dropped I decided to look into it, and ended up liking it a lot more than cinnamon.. Didn't feel like setting up/downloading things again when distro hopping so I back ported kde from kubuntu.
