Macbook pro screen flickering sometimes

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. Its amazing you have a screenshot.

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.

I have the same issue with my 5 days old 13" MacBook Pro 2019.

I found this on the internet:

Seems like it's a software issue and we'll have to wait for the new update..

Have you tried Safe mode?
