Screen brightness problem on MacBook Air M1

[zulicheg]

Hello everyone!

After updating to Sequoia 15.4 on my MacBook Air M1, the screen backlight periodically started to float. You just sit at the laptop with constant lighting, and the screen gets darker and then lighter. The only thing that helps is turning it off completely and turning it on after a minute. I think this is a problem with the update, since this has never happened before.

It is also interesting that when this happens, for some reason the standard picture of sequoias on the desktop becomes lighter and from a different angle and does not change to its normal position until rebooting.

Does anyone have the same problems after updating to Sequoia 15.4?

Try to turn OFF the display auto-brightness, and see what happens.

Of course you can do it this way, but before the 15.4 update everything was fine with the automatic settings enabled.

I wonder if anyone else has a similar problem after the update.

Things break.
It's just to troubleshoot your issue.
I recommend to run the hardware diagnostic as well.

Diagnostics does not find any errors.

Updating to Sequoia 15.4.1 did not solve the problem. I found that the problem is WindowServer. For now, as a temporary solution, I use sudo killall -HUP WindowServer so as not to completely reboot the laptop, in fact, it reboots the graphical shell and all open programs, you could say "accelerated reboot without resetting the uptime".
