I am not sure if my pocket has a v1 display but it is from an early crowsupply batch. When using swayidle with “power off/on” it comes back up with a nauseating flicker which is only fixed by shutdown the machine and restarting it. This pocket has been upgraded with the RK SOM.
So yes, sounds like the same problem. I actually ordered a display on ali express because I thought it was broken but haven’t installed it yet and now i see messages like this popping up here (see also Screen flickering after a GNOME screen blanking).
