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
X11 or Wayland? Try switching between them to see if it persists
Was yellow with x11 plasma and cinnamon except cinnamon on Wayland was normal, I tried switching to lightdm and it was giving me errors.
I found someone had same issue a day before on mint forums. Apparently it was a graphics driver from oibaf ppa.
I forgot I had timeshift setup monthly (changed it to weekly), so I restored it and everything looks fine. I didn’t lose anything because I was so busy that I only had energy to played Factorio after work which are steam cloud synced.
