Screen flicker with USB-C charging
#5
Just to confirm that after a recent kernel upgrade (I lost track when but it might be related to when the DP patch was introduced ?) I now have the exact same problem, including to the current kernel 5.10.2 :

When computer turned off:
USB-C PD charger works.

When computer turned on:
USB-C PD charger and cable: After a few seconds, the "charge icon" starts to blink (i.e.: laptop battery charger sees the cable constantly plugged in and out in quick successions) and the screen starts to blink (i.e.: power manager constantly switches brightness between "on battery" and "on charger" level).

USB-C to USB-A cable and plain USB-A "Smart Charge" port on the same charger: works normally
Barrel to USB-A cable : works normally too.
