I have noticed that when Illustrator is open, my screen brightness changes.
This seems to happen whenever the overall "brightness" of the images displayed on the screen change. For example, if I zoom out from my image,
a majority of the screen is grey due to the program background, and my screen fades to a noticeably darker brightness. If I zoom in on a darker section of my image,
it becomes even brighter. I've had a look through the options but couldn't see anything that would help with this
Check 3rd party Apps, like computer performance settings apps. In my case, I've had the same issues like You, but on my desktop computer and using MSI X Boost App for overclocking. When I turned off this app everything went to normal. Also, You can change adaptive brightness settings if u are using a laptop with an ambient light sensor.
Best regards,
