2018 macbook pro. is anyone else's true-tone display developed an issue of rapidly flickering between hues? it's definitely true tone because turning it off stops the flicker.
Yes! My 2018 MacBook Pro is also doing this. I first noticed about 7-10 days ago. It mostly happens in the morning when the sun is rising or in the afternoon during sunset, but this does not excuse it, this was NOT a problem when I bought it. The issue was sudden and very recent.
Glad to find it's not just me and I'm not going crazy. My plan is to record clips of the issue and then go to the genius bar.
Yep same here on my new MBP 16" I9...
Sometimes I see colortemperature flickering
And the last two times I have woken the computer up from sleep a new strange thing happened:
The display wakes up with very little contrast - like you put the brightness control to max and contrast to minimum... When this happens - I am able to go into System settings / Display and switch Truetone off and then on - and the normal contrast and colors are correct again...
Must be software related so hoping for a fix in the next Catalina release .
1. Both my previous 2019 13" TB and current 16" would flicker colour temperature, and
2. I have just now experienced the low contrast issue for the first time and toggled True Tone to fix it
Bonus round: When I wake my 16" MBP after letting it go to sleep with a monitor connected, the monitor remains off and the laptop screen flickers on and off sort of like when you connect a TV and it is (I assume) negotiating capabilities/calibrating. It does this ad-infinitum when ever the monitor is connected but the laptop screen does work fine if you disconnect the monitor. I have to reset the laptop in order to reconnect the monitor. I haven't bothered to dig into this one so for the moment I get around the issue by running caffeinate before stepping away from my desk.
