Graphic glitches are no more, but the only thing left strange screen flicker, for example, when the program Blackmagic Disk Speed ​​Test is running. How can I fix it?

Yes, the problem is specific to certain apps (most notably, Google Chrome) when they display certain gradients or patterns.

Solution: Use apps that don't have the problem (Firefox, Safari).

Do you have a flicker on the window of the program Blackmagic Disk Speed ​​Test? Please check on the original MacBook Air and ProBook

Do you have a flicker on the window of the program Blackmagic Disk Speed ​​Test?

Yes, especially at higher brightness levels.

Please check on the original MacBook Air and ProBook

I will check (and the other test sites) on my MacBookAir6,2 later today (not near it right now).

Interestingly, the problem is not present on the Lenovo U430 I have here.
