Every 20 - 25 seconds the standard screen flicks to the 'artist info' screen for approximately 0.5 seconds, then back.
This should not happen.
On my test system RP3 with original 7" touch it works like it should.
It switches to the screen saver after the configured time.
It stays there and only switches back when i tap on the screen.
It also works with a HDMI monitor and mouse attached.
The same thing happens on my local browser running chrome on a PC, which is definitely not a touchscreen!
I will try to reproduce this as soon as possible.
