Chosen Solution
My Macbook Pro 13” early 2015 shows a really strange glitch or flicker problem since a few days. The issue first started appearing a few days ago after using the built in screen recording tool of macOS. It seems to intensify under heavy use. See attached video and photos. What I have tried so far to fix it: reset NVRAM + SMC; the issue persistssafe mode (reboot + shift); here I wasn’t able to reproduce the issueApple diagnostics (reboot + D); didn’t report any errorsApple recovery (reboot + R); here the issue does not show up eitherreinstalling macOS via recovery (not clean install!); after doing so the issue persistshooking Macbook up to external display; the issue also shows up there (which makes me conclude it the issue is not caused by my internal display)uninstalling all unnecessary software + removing login items; no differenceactivate color filters via accessibility, activate different color profiles in display preferences (found these tips online); no differencecreating new empty user; the issue was also appearing there (even on the login screen it shows up occasionally, but never in the boot screen with the Apple logo and white progress bar)interestingly, the issue shows up in screenshots (see attached)even more interestingly, the flicker seems to affect everything BUT the cursor; when I move it through areas that are flickering it moves OVER them without being affected What I see as possible causes: software issue, GPU or something Logic Board related. Though the cursor not being affected speaks against a hardware problem in my understanding. My last ideas are to upgrade to Monterey (currently I am on Big Sur) and, if that doesn’t show a difference, wipe the whole machine and do a clean install of Monterey from a stick. Other than that I am out of ideas. If anyone has any tips that would be really helpful.

What you are seeing is video RAM errors! The way you can tell is your snapshot is capturing what is held in the the Displays RAM buffer. Sadly, there really is noting you can fix here as one or more of the RAM chips is failing. Time for a new logic board MacBook Pro 13" Retina Display Early 2015 Logic Board Replacement
