In game bug

So today was patch day and everything was fine, now after a few games that i've played, i noticed that my mute/unmute buttons and my camera control/ping buttons were only black squares. I have no idea how to fix this and It's on the live servers so I would appreciate some help because.

Its like the icons for those buttons failed to load or are bugged. This affects nothing in gameplay but it still is unproffessional.
