macbook pro screen flicker

I just bought a 2019 Mackbook pro 13" running 10.14.6 and I noticed pretty much right away that every once in a little while the bottom portion of the screen will do a really fast flicker. It'll do it only one time and it kinda happens at random. Is anyone else experiencing this issue or know what could be causing it? I updated it just to see if maybe that would help but it still seems to be having the same issue. Any help would be much appreciated.

I just purchased a


mid-2019 MacBook Pro (MacBookPro15,2)

2.4 GHz Intel Core i5

Model A1989, Product Z0WQ

16GB RAM 2133 MHz LPDDR3

Intel Iris Plus Graphics 655 1536 MB

MacOS Mojave 10.14.6, Dark Mode


I too have a similar issue. My flashing/glitch is towards the bottom of the screen like yours but only shows up for 0.5s or less.. and is usually bright magenta or green. I cannot intentionally replicate the issue, it just seems to happen randomly or at least when I have several applications running for school.. ie Word, PowerPoint, Safari (multiple windows each with multiple tabs), iCal, Mail..etc.


From what I have read, the issue might be related to the computer's sleep/awake settings and or the auto dim settings. I haven't had any issue after performing the following steps


1) Reset the SMC https://support.apple.com/en-us/HT201295

2) Reset the NVRAM/PRAM https://support.apple.com/en-us/HT204063

3) Turn off "Automatically adjust brightness" and "True Tone"(System Preferences > Displays > Uncheck these options)

4) Turn off "Night Shift"

5) Turn display off after 15 minutes. (System Preferences > Energy Saver > Battery > Turn display off after 15min)


No idea which one actually solved the issue but hope this helps.
