Hi all. I got the base 15 inch. I’ve noticed a weird behavior with the display. Every now and then, mostly when i click to interact with the os, i see a fast screen glitch behind the active window. Sometimes behind all windows sometimes just behind the active one. This must be a widespread issue as I returned the macbook and got another one. Same model but different store. Same issues. also, happens on external displays as well as macbook display. I originally thought its a failing graphics chip, that’s why i returned the original MBP. But since the issue is happening on my other one as well this might be a driver issue perhaps. any experience? Update (05/22/2020) @danj I got one couple weeks ago used that was in a pretty bad condition (i only really found all the issues after buying it) and for that reason when I saw the flickers I figured the graphics chip is failing and I just returned it while I could. Couple days ago I got another one, still used but in a great condition this time, from an actual store with a one year warranty. And when the glitches happened there I figured must me something other than the chip failing then. Update (05/22/2020) @danj Hey, I managed to catch a video of the flicker. Again, note it happens without any script running as well, and happens completely randomly whatever apps I have open or what I am doing. Please check the video here: https://youtu.be/iLkrxIqlqeY Here’s the snaps from it:

The glitch!
The only thing I can suggest is see if you get an error when running the onboard diagnostics. Restart your system and press the D key to enter into it. Did you get an error? I have not seen a fleeting glitch like you have described. Update (05/22/2020) OK, now I understand why you’re getting the glitch! The patch (RealMacMods NoCrash Utility) you put in resets the VCORE voltage set within the firmware, to solve a crash issue some in this series had. This patch had its own issues! Unless you are encountering the shutdown event issue I would not recommend using it at all. This patch is not a real fix its just a band-aid! The real fix it fixing the logic board CPUVR power MOSFET’s as my friend at TCRS shows in this vid Why is your Late 2013-2015 A1398 MacBook Pro randomly crashing? CAUSE AND SOLUTION
