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.
I’m running mint 21.3 with plasma 5.27.11
No option on plasma 5 that I could find, I learned that it was a graphics driver that updated and caused all this, thankfully I had automatic backups setup.
