Title: Raspberry Pi 3: a small rainbow square on the top right of screen Status in snapd: Fix Committed Status in linux package in Ubuntu: Invalid Bug description: I'm working on the WD/nextcloud project, and found this issue Download the UC16 for Raspberry Pi 3 from http://releases.ubuntu.com/ubuntu-core/16/ubuntu-core-16-pi3.img.xz unxz , dd the image to sd card and boot up the system. There is a small rainbow square on top right of HDMI monitor. From RPI forum: https://www.raspberrypi.org/forums/viewtopic.php?t=82373 If the voltage is under 4.65V, firmware displays a rainbow square on top right of screen and power LED goes off. But for UC16 the rainbow square is always there even the voltage is sufficient, but the power LED works properly. So I also check 1. Ubuntu server for RPI3 from here: https://wiki.ubuntu.com/ARM/RaspberryPi This RPI3 image works properly (if the voltage is not sufficient, rainbow square shows on the top right of screen, if it's sufficient, no rainbow square shows up) 2. Rasbian (jessie lite): https://downloads.raspberrypi.org/raspbian_lite_latest This works properly too, and the official Rasbian was released with the latest firmware, so the rainbow square changes to a lighting icon It looks the firmware might be old in UC16? so the under-voltage warning doesn't display correctly.
