Confirmed that the bug is fixed in the 4.10 kernel series.
Further confirmed that this is down to the i915.enable_psr parameter:
Linux 4.8 with no command line => flickering (enable_psr defaults to on)
Linux 4.8 with i915.enable_psr=0 => no flickering
Linux 4.10 with no command line => no flickering (enable_psr defaults to off)
Linux 4.10 with i915.enable_psr=1 => flickering
** Package changed: nvidia-graphics-drivers (Ubuntu) => linux (Ubuntu)

flickering irregularly. It only happens with kernel 4.8.x. No
flickering problems when manually switching back to kernel versions
4.4.x at boot.
