Hello, I have a problem with my mac since few weeks now. The white becomes grey and flickers all the time. I have no problem with another color. I can watch a movie, or a video on YouTube the colors don’t seem alternate. It’s mostly the background screen, like on the Google page, or on the software page for example, but if I replace the color by an other, the problem disappears. When I move my cursor with my trackpad or with an external mouse. The flickering stops while i keep moving it. Best Update (10/31/2020)

On this one we cannot clearly see, but the screen is flickering very fast, but if i just put the background in black it stops. And this is what happens when i connect to my TV screen

But the screen on my laptop is not affected.

Ouch! That implies the issue is within the logic board graphics services. This series uses the intergraded graphics engine within the CPU and the systems RAM. Then the output is pushed to the MUX drivers to pump the video to the two Thunderbolt ports and the internal display. Somewhere in this pathway is where the issue is. If your system is covered by AppleCare+ Apple is on the hook
