Hello, I would like to note that I think that I also have something related to this bug - although with the normal 1920x1024 panel (on XPS 13 9380) with a fresh Ubuntu 19.04 install (so kernel 5+) - I did not test the OEM Ubuntu 18.04 LTS.
The screen "flickers" from time to time (perhaps linked to refresh?) barely noticeable during the day but a lot more often at night with redshift / gnome night light enabled.
