Hello. I've noticed every once in a while, my screen will flash black really quickly on and off. It appears to mostly happen when I close my Macbook Pro and then open it again, or when I log in to my computer. If I restart my computer or close the lid and log back in, it usually stops flashing. Any ideas as to what could be causing this bug? Has anyone else seen this? Thanks.

Maybe you can try to upgrade your GPU driver?

@planet clicker You may have a corrupted PRAM/NVRAM or SMC. Resetting the PRAM/NVRAM (Parameter RAM/Non-Volatile RAM) and SMC (System Management Controller) can sometimes fix strange display behavior, including screen flickering.

  • To reset the PRAM/NVRAM: Shut down your Mac, then hold down Option + Command + P + R for about 20 seconds while it starts up.
  • To reset the SMC: The steps will vary depending on your MacBook model. For recent MacBook Pros with a T2 chip, shut down your Mac, press and hold the power button for 10 seconds, then release and restart.
