Rainbow box in top right corner

On one of my Pi2 installs there is a rainbow box in the top right of the screen that constantly fades in and out. It’s even there during video playback.

It’s only on one, the other one is fine so it might be a glitch that a reinstall would fix.

But I thought I would bring it to your attention just in case it’s something you would like to know about.

Power problem which can cause all sorts of issues, see: https://osmc.tv/help/wiki/pi-power

The rainbow box indicates a PSU problem. Google pi2 and rainbow box for details but in short your PSU or USB cable isn’t giving your pi2 enough juice.
