So, initially my toolbar was dark and semi-transparent..ish. Now, all of a sudden it changed to this really bright greyish-blue color (it also made all the icon on the right side of the toolbar much, much, smaller for some reason!) and the top of the screen's tabs is bright blue now, too! This is very distracting. I need the old one back. I tried restarting the computer. It was back to normal for a bit but then a couple minutes later it happened again. Help plz!
