2021 MacBook Air Screen lighting randomly gets dimmer and dimmer. I need to manually adjust to brighten up the screen so I can read it.

Not sure why this is happening. The screen light keeps dimming once I log on. I need to tighten it up with the F2 key to be able to see the screen. Am I not finding the right adjustment switch?

macOS Ventura flickering screen I updated my Macbook Air M1 to Ventura on Monday 24 Oct. Within a few hours my screen started to flicker. I rebuild the machine using a USB drive (Create a bootable installer for macOS - Apple Support) After a few hours it started again. I notice this happens when I am using IntelliJ Idea Ultimate. Has anyone else encounter this issue? Perhaps when doing something that will use up a lot resources? I don't mind going back to Monterey I just hate the long process of rebuilding/setting up a machine.

Cannot toggle "Prevent automatic sleeping on power adapter when the display is off" Off There seems to be a bug in MacOS Ventura. I wanted to download something large overnight, so I toggled on "Prevent automatic sleeping on power adapter when the display is off" which can be found by going to System Settings > Display > Advanced. Now the reason is over, I want to turn it off, however this is not possible. It is like there is an elastic mechanism that keeps the toggle on no matter what I try. Simply pressing on the left part of the toggle doesn't work, dragging the toggle to the off section automatically returns to on immediately. Any help?
