Hi Samuel,
I have the same issue with my device. Paid a mint for it. When you aren't using it hard it will not flicker until it heats up, then it goes nuts. They will lose a lot of business as people are now using there devices during this pandemic. Microsoft knows about the defect that they manufactured but they wont provide a recall on their devices or provide warranty to ones who have the issue. They are only covering devices for their mistake for 3 years. If you notice it after they wont help you out, but make you pay for what should be their fix. I know its frustrating. On their support page they say that a very small amount of people are having the issue but that's not true its a pandemic that is known as "Flickergate". I have contacted Microsoft many times now and still they haven't provided real solutions to this issue, and don't want to admit to this problem, but eventually im sure they will do something, they have to if they want to keep their clients and a good reputation, please let me know if you get help. Thank you
