Graphics Driver Issue?

My brand new 16" has already exhibited twice in 3 days what I hope is a glitch: for a few seconds, the Safari and Mail frames turn from grayish to a light, brighter blue. I am really hoping this is a software issue because, other than that, there is no ghosting or smearing. Plus, the machine is very cool (I had to return the previous one because of heat and fan issues).
Anybody else having this issue? Possible for it to develop into a more serious issue?
 
Just happened again, only now the whole Safari window turned blueish.

Nobody else experiencing this?
 
I have just turned it off to see if it makes a difference.
 
I have just reset the SMC and turned True Tone back on. My display turned blue right away.
I went to Terminal and there was some stuff showing there already. Do I erase everything and enter the code? Sorry, I have never used Terminal.
 
Right before using the Terminal, 10.15.5 came out so I decided to install it and see if it solves the True Tone issue. Fingers crossed, no problems since.

10.15.5 has not solved the problem. I ended up entering the above code in Terminal. Wait and see.
In the meantime, I have discovered what a mess News and Messages are when it comes to scrolling. Messages, at least, the cursor goes all over the place and, before you know it, it stuttered all the way to the oldest message in the conversation. I have unchecked "Use font smoothing when available" and it helped a bit. Very little.
It happens that I had access to a 2016 13" MBP and looked at News and Messages. Just as bad.This leads me to believe that the 2019 16" MBP graphic card is no better than a 4 year old 13"? After paying such a premium for it!
 
Can you take picture next time it happens? Not sure if its display corruption or the GPU glitching out.
 
I had the chance to look at another 13" and, when there are lots of photos throughout the conversation, the same stuttering happened there.

I don't see any stuttering on my 2020 13 inch. Even when I have multiple programs like Excel, Spotify and Messages running in the background
 
Something is definitely wrong with truetone on my 2020 MBP 13 after the recent supplemental update.
When deactivated, everything looks warmer like it's supposed look while activated. However, when I activate it, the color tone does not change at all, then suddenly flashes to a blue, cooler color. Something with the software is DEFINITELY off...

I had the same issue. Entering the following code in Terminal solved my issue:
sudo pmset resetdisplayambientparams

This is because of the dedicated you and Igor switching and not being calibrated right. dswitch you can use and toggle it on and off to see, the system will do this often during youtube.

Unfortunately that didn't solve it for me, and it's happening more often. (I've had my machine for ten days.) I really hope it's a software issue that can be addressed in a future update.

I'm now trying turning of TrueTone to see if that's contributing to the problem.

This issue is erratic for me--the sudden tone changes will keep happening, even after the terminal command, multiple restarts, and a NVRAM reset. But then after waking from sleep, the problem will randomly be gone. After I wake it from sleep later on, the problem returns.

This makes me a bit relieved because it's clearly a software issue with true tone, rather than a hardware issue that requires me to send my machine in for repair.
 
Have you use switch to see if the gpu switches when this happens? I’m finding it only happen when the gpus toggle obviously their not both calibrated correctly
