A few other issues I encountered when testing on the Pinebook Pro:
1) Natural scrolling setting doesn't work
2) WiFi doesn't come back up after suspend. Restarting network-manager brings it back up.
3) Video out via USB-C doesn't appear to work on any of my docks
One other thing I noticed: in settings 'About' panel, under graphics, it doesn't list Mali T-860 (Panfrost) but rather Unknown
