Occasionally getting washed out or faded display color
Hi, I have MacBook Pro Mid 2012 with os Catalina 10.15.7 installed. Recently I started facing a problem with my display. Occasionally I am getting faded or washed out negative appearing color on my display. It automatically resolves on restarting. It stays normal for sometime then the problem starts again. Sometime the display stays normal even until the whole battery is drained out of charge. It started few days back when I put my MacBook on charging and left it for 2 hours while it was on. When I came back and woke it up from sleep mode, the screen looked washed out and negative in appearance. The display stays normal most of the time but the problem occurs mostly when it gets overheated or after plugging in my charger. I am still confused about the main cause of the problem. What could be the possible solution if the problem is due to charging or overheating?
