MacBook Pro screen issues

Hi! At the beginning of March I started having this issue with my screen. Upon startup the display will be fine but then as I use it the issues will always appear. It starts with lines going horizontally across the top of the screen, after some time those lines will then start flashing, and then after several hours of use the entire screen will display what I would describe as a shadowing of previous things that were on the screen. I'll pop some images below as I'm not sure the worded description will be entirely clear.

Due to Covid I've not been able to take it to Apple to check what might be the issue, don't suppose anyone knows what might be the cause?

These quick tests will help you isolate whether that is a screen defect or a graphics subsystem defect.

Connect an external display or TV set. If the artifacts are NOT seen on the external display, that suggests that the built-in display is the problem.

Take an Internal screen shot (NOT a photograph). if the defect IS NOT reflected in the screenshot, that strongly implicates the display itself.

You can arrange for a mail-in depot repair by starting with the "Contact support" link at the top of any forum web page.

Thanks for the quick reply! It doesn't appear on internal screenshots. I decided just to double check with an external screen and that didn't display the issue either.

Though when I switched the screen optimisation from the MacBook Pro to the TV I plugged it in to I did discover the issue also stopped appearing on my MacBook screen as well. But would reappear the second I switched optimisation back to the Mac.

So I'm not entirely sure what that suggests the issue is.

If you used [√] Mirror Displays, that sets both displays to a "compromise" resolution and they use the SAME display-generator. That just says you do not see the artifacts with a different resolution.

It does not change that this is likely to be a display defect, based on your experiments.
