A brand new Dell XPS 13 9380 preinstalled with Ubuntu 18.04 flickers to the point of being totally unusable.
I have upgraded since to 18.10 and 19.04 with no changes. I have tried several combinations of the i915 parameters fastboot, enable_rc6 and enable_fbc to no avail.
Examples of flickering are here:
