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.
It work none the less, I'm at a stage in my life I rather have stability rather then bleeding edge, I used to enjoy fixing things, till issues started happening when I really needed to work, instead of spending hours fixing wifi drivers.
Only reason I had oibaf drivers was because I was once trying to get game scope to fix a bug with mouse controls on war thunder for Linux. Was dependency issue hell, so after 2 hours I ended uninstalling it and not trying the game.
