Alright, here we go. I have the kernel listed above installed: Linux shadeball 5.2.0-9-generic #10~bfo110511 SMP Tue Jul 16 13:17:28 CST 2019 x86_64 x86_64 x86_64 GNU/Linux
I then went into the Power settings and turned Dim Screen When Inactive to off, Blank Screen to Never and so far there have been basically no flickers. There may have been one or two, but I can't confirm that I saw them and cannot reproduce them. I have tried it both on AC power and on battery, and with success on both.

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.
