Bug with screen brightness

Hello,

Just installed Garuda with I3 and got a problem

Every 3 seconds the brightness change from high to low then low to high, like a very slow flickering...

It almost fells like my laptop is constantly entering into power saving mode just to leave it a couple of second after.
So I tried to unplug but.. nop, brightness is till switching again and again.

And yes it started as soon has I was in the Garuda installer.

I believe you are you are experiencing the redshift (day/night) program. I had no issue on a desktop, but i3 on both my laptops disliked this. Remove the item identified in this post, and it will hopefully help with that.
