Hi and thank you for replay
I don’t have any random lightnings effects. The “only” visual problem is that colors are washed out and everything seems much brighter that usually even when changing brightness from 0.5 to 0.2 and yes I have tested both with audio forced to HDMI-only and with audio disabled with no success.
I have already latest rpi_ws281x at version 3.0.1 so it dosen’t help
$ sudo pip install --upgrade unicornhat
Requirement already up-to-date: unicornhat in /usr/local/lib/python2.7/dist-packages
Requirement already up-to-date: rpi-ws281x>=3.0.1 in /usr/local/lib/python2.7/dist-packages (from unicornhat)
$ sudo pip install --upgrade rpi_ws281x
Requirement already up-to-date: rpi_ws281x in /usr/local/lib/python2.7/dist-packages
3, My big problem is that every time running Unicorn-hat python scripts is locking my Rasbian or making it read-only. As long I don’t use Unicorn-hat scripts Rasbian works without any problems. I can also run others python scripts without any problems.
