Apparently the issue with the new RX regards a light leak affecting some cameras that happens in direct, harsh light with the EVF engaged. Affected serial numbers are follows (translated from French):
If the serial number of the DSC- RX1RM2 apparatus is comprised in the range indicated below, it can be concerned:
Product serial numbers from 7360021 to 7360551
Product serial numbers from 7760004 to 7760052
Product serial numbers from 8160021 to 8160357

Luckily, my camera's SN starts with 631
