But just to confirm, I think the patched kernel did improve the amount of flickering.

I ordered the official Ubuntu edition from Dell which came with 18.04, but I've since wiped it and installed 19.04 from a fresh ISO download. This is the non-touch non- 4K version (13-inch 1080p). Every so often (maybe a couple of times per minute), the screen flashes brighter, as if the brightness has been turned up momentarily and then back down again. I previously had an issue with the brightness / colours changing slightly when I opened menus or if the screen content changed slightly, but I fixed that by disabling Dynamic Brightness in the BIOS. It is definitely a better experience with that turned off. However the screen flashing still persists. I booted a live image of Fedora 30 now that it has been released, and so far I have not seen the screen flashing, so I do not think the hardware is faulty. I ran apport-bug, so hopefully the collected information has been attached. Thank you.
