If this were Windows I’d suggest drivers or monitor connection (doesn’t look like a monitor problem but you never know what unplugging it and plugging it back in can solve.). It looks like something is confused and unable to interpret a lookup table, or has lost its ability to access… I don’t know what I’m talking about, have you tried turning it off and turning it on again?
I feel like justice is going to be dealt by the people and not by the system we agreed to live in, and that isn’t the system I agreed to live in.
