True Tone Bug on iMac 2020?

[DurianMaybe]

Hey peeps,

Was wondering if anyone has had a True Tone bug happen with their 2020 27" iMac? Just got mine a few days ago and tonight half the screen displayed True Tone (smack down middle of the screen) while the other didn't. Fixed by unchecking True Tone and checking it again. Not sure if I should be worried and calling apple support so wanted to ask here first - this is my first iMac after upgrading from an MBP from 6-7years ago so still adapting lol

TIA

I haven't seen that on mine (5500 XT GPU) but it does sometimes make drastic changes to the color temperature instead of properly fading to it.

There was a post here where a user was able to get True Tone on one side only by changing to a different resolution.

Okay something truly odd is going on here. Last night, 4+ hours of usage, no flashing white line. This morning I use it for a couple hours, nothing. I'm out all day and get home about 3 hours ago and have been using the iMac since, again no flashing white line. Then as I'm using my iMac and...

That's exactly what my screen looked like! My gpu is the 5500 xt though so that's interesting... will keep monitoring it and really hope it's a software issue

I was able to replicate this bug as well. Apple is really hitting it out of the park lately with their QC. 🙄

Hmmm... I guess this is because the display is internally connected to the GPU via two DisplayPort links, each of those handling half the screen.

Had the same issue a few days ago, also changing resolutions.
Easily solved and didn't worried about it, but definitely , Catalina is a piece of s*** . I don't think it has to do with hardware. I've run through several problems coming from High Sierra, which for me, was rock solid.

Guess waiting on the Big Sur update later in the year then :/ - was using Mojave on previous Mac and did not notice this many bugs (also noticed the male app just pinging in your face when you're doing other stuff lol)
