Phone display is jittery / cutoff when using USB-C video out
The phone display seems to have some kind of horizontal sync issue whenever I use the USB-C video out. I can reproduce this on my NexDock or using the included USB-C dongle to an HDMI monitor. The output video on the monitor doesn't show any display artifacts and looks great, it's only the phone screen.
I don't notice this issue using phosh on Arch ARM, so maybe there's already a fix upstream?
