Hi, after upgrading to Yosemite (now on El Capitan public beta), I've had trouble with the menu bar icons. It only appears for about 2 seconds and disappears. They still function as they are supposed to but I cannot see them. I originally though this was an Yosemite issue but the problem persisted in El Capitan. If anyone knows what maybe causing this/how to fix it, it would be hugely appreciated.
