Can you try this for me (display flicker unrelated to vega)

[Ploki]

Disable truetone/auto brightness.

Go to colour, option click "calibrate" to get advanced settings.

set to full brightness.

Try to calibrate your display as accurately as possible (follow steps)

When coming to gamma, try setting it a little darker than native (higher value, 1.7, 1.8?)

When coming to temperature, try setting it a little cooler than native (6600, 6700?)


Questions:
- does the display suddenly turn darker when you save your profile?
- does the display flicker when you enable/disable "auto adjust brightness" on the new profile?

Thanks.

edit:
I have had this happen on 2 2018 Macs already 13" and 15", spanning from 10.13 to 10.14.2... so i doubt it's a hardware issue

anyone?

@nutmac pointed me to this thread in the MBA forums:
https://forums.macrumors.com/threads/2018-mba-backlight-flickering-automatic-brightnes.2160821/

I'm surprised nobody in the MBP noticed this, I've noticed it on both the 13" and 15", and this bug if i recall correctly has been going on since at least 10.13.6 on the 2018 MacBook Pros.

Seems like a lot of steps to get this issue to occur. I am not surprised it was not discovered previously.

I routinely do this on all my new macs. I prefer a littler darker and a little cooler display.

I'm surprised that it was discovered over at MBA forums and not here

When i will get to my 2018 models i will try on those too...but even on my late 2018 MBP, even i dont have true tone but if i follow the exact those steps i get a little of flickering. That MBP is on High Sierra, i will try on Mojave on my MBP models later

Reading this thread I lol’d. I agree with @jerryk, lots of steps, with specific values to create an issue.

 

[fokmik]

yes indeed, it is just a minimal issue but still this kind of test it should have been done by Apple's QA team that gets paid for this

I don't know how specific values need to be really. this is how i usually do it and can be 100% replicatable since this is how I did it on the new 13" as well. However, as far as i know most manual calibrations trigger it.

I'm aware it's not a huge issue but it's a little bit annoying, i've been doing this on my new macs for the last 10 years.

Most people turn on system, and just use it. Few calibrate their displays. I bet fewer than 1 in 1000. I hardware calibrate with a colorimeter, but I bet that is 1 in 10,000 or even fewer because of the costs.

FWIW, I do not have this issues with hardware calibration.

Works fine on the Ultrafine with mini too. Must have something to do with auto-brightness and maybe truetone
