maybe ignore it?

If I were keeping the computer I would, but I'm hoping to sell it, and I'm sure if a buyer sees this they would be wondering if it's ok. In the meantime I've seen lots of posts online about similar issues with upgrading to Big Sur on older MacBook Pros: glitching and/or flickering screens during startup/shutdown and in normal use.  Today I'll be erasing the drive and re-installing the OS to see if that fixes it  🤷🏻‍♂️
