My volume logo is "deformed" or "broken" whenever I press volume up/down. However, when I click on Reduce Transparency, it looks perfectly fine (aside from the black triangles in the corners) How do I fix this?
MacBook Pro, OS X Yosemite (10.10.1)

Starting up in Safe Mode should solve this graphic glitch.

We have to wait until Apple fixes the issue.
Best.
