Screen Brightness Icon Pops Up Unprompted

Hello,

I have a Mac Air that is not even a month old. Today, the screen brightness icon has started popping up as if I was hitting the brightness button on the keyboard, except I'm not. It'll go away, then pop up again several seconds later. I've tried restarting my computer, to no avail. It is driving me insane. I'm trying to work around it keeps getting in the way. Has anyone else had this issue? Why is it happening and how can I fix it? I tried reporting it as a bug but I can't sign in. The username and password fields don't work. Please help!!

MacBook Air, OS X Yosemite (10.10.2)

I have this issue on my 2009 21.5 inch iMac running OS Sierra 10.12.6 that began only yesterday. It seems to be related to the brightness control setting in the system preferences. The slider is not working and will not stay at a bright setting. Both issues started at the same time. The screen icon pops up occasionally and remains for awhile, goes away, comes back. It also does not work for setting the screen brightness. That icon is also activated by the keyboard (usually) but I use a Logitech wireless keyboard and there's no key for activating brightness - only sound.

Have you tried an SMC reset?
