Also had a line going from the middle right side of the screen right to the center, a black line perhaps a couple pixels in height. That persisted between turning off/on, but went away when I chose Picture mode: Movie, then back to my default of Standard.
There are definite firmware bugs in this beast.
It's not all that unusual for literally any electronics device to encounter data collisions and require a restart to flush and refresh - It occurs with PC's, Printers, Servers, Cisco Switches, Copy Machines, VOIP Devices and it's really no big deal unless it's replicated regularly/repeatedly and you are referencing one event and it's does not equate to a firmware flaw at all if the event went away.
I buy for and manage a large enterprise Network and virtually any electronics can encounter what you describe and certainly not something needing an RMA unless you have a pattern that doesn't go away So your panel had a temporary hiccup restart and let it refresh and it seemed to have done that. If a self calibration makes any temporary artifact go away what's the fuss unless it remains a constant.
Consumer Electronics require a little patience and of course understanding as to what's going on inside and differentiating a temporary artifact from a static event that doesn't go away. Good Luck!
