When I first started the unit it had big problems with flickering that grew when battery drained. It got better when I disabled dimming in the power management but it didn’t go away completely. After some charging cycles I find the problem have diminished but is still present, especially when battery is low and the screen brightness is dimmed.
I have a related problem with the screen in which it emits a high frequency noise which is more apparent when brightness is turned down. Its still present when fully lit though! When there’s a lot of sound in my surroundings this is not a problem but it is quite annoying when alone in a quiet room.
I'm experiencing the exact same issue as Meatball regarding the flickering screen when on battery. When on AC power, it's fine, but as soon as I unplug it, any graphical related activity (even moving the mouse) causes random massive headache-inducing flickering. It seems to get worse as time goes on... It is still present with all dimming options off and happens at any brightness level as far as I can tell. I'm also hearing a high frequency whine when it switches to battery power though I haven't paid attention if it happens at different brightness levels. It's happening on both the default Debian install and on ayufan's rock64pro bionic-mate-pinebookpro-0.9.14-1159-armhf. I'll report back on other observations I make regarding this issue.
