Flickering lines on my MacBook Pro 2023 16" Screen
I have an odd problem that just started happening recently. I have about 3 lines that flicker on my MacBook Pro 2023 16" screen. Two are vertical about 2/3 from the left side of the screen, one larger than the other. Then there is one that is near the top of the screen and horizontal. Images don't show it but the lines kind of flicker.
I most often use my laptop with two external monitors and it's not showing up on them so is something specific to the laptop's screen. Is this something that could possibly be fixed in settings or somewhere else or is it definitely a hardware issue? I have AppleCare on this machine and if necessary I can go to an Apple Store but am hoping there's a chance I can avoid that. The below image shows the line across the top of the screen and the two vertical lines. Also below is a link to a video showing the flickering.
