Buffer icon

There’s a little I’m pretty sure buffer icon showing over videos when playing. Could I hide this somehow? See attached.

I’ve never actually seen it, but I believe the “rainbow icon” denotes that your power supply isn’t outputting enough power to the pi.

Ahh yes, here’s a quote from the pi forums this was added on the B+ forward:

Under-voltage warnings said:
The B+ has an under voltage detect trigger which results in the power led going off when voltage drops below about 4.65V.
The signal is also available on a gpio line (GPIO35).

Latest firmware update will display a warning symbol in top right of display when this is detected.
It will also disable turbo mode while the warning is displayed to try to reduce the chances of crashing.

Definitely low power.

You need a power supply of at least 2A for an RPi2 and 2.5A for an RPi3.
