I found the problem yesterday.
The regression is that the gradient (which didn't appear at all before)
now only occupies the middle 50% of the screen. This means it looks
squashed and different to the login screen. The top and bottom 25% of
the screen are solid colours.
It looks like a problem

I was wrong. I can see the same bug in git builds. It's just not obvious
when you're not coming from the login screen.

Thanks. I have confirmed on a third cosmic machine the same bug in
3.30.1-2ubuntu1.18.10.1 :(
However, when I apply the above patch to gnome-shell git (either master
or gnome-3-30 branches), there is no bug at all. The patch works fine in
my own local builds from git.

I don't have the time to do a testround again, but I can give pointers
for whoever has time to have a look:
The patch is

systemBackground = new
It does make this bug worse. The original bug was barely noticeable, but
with that fix it's really a bright and obvious glitch.
What we could do is release the SRU but just keep this bug open.

Daniel, ok you consider the fix here as problematic. Do we believe it's worth
unvalidating the SRU over it though? We have enough difficulties landing
gnome-shell SRUs fixing at the moment and the touch event one included in the
same update is important to oem.
If the background change is not
Yes, I have now tested the proposed fix on two separate fresh
installations of cosmic. One HP and one Lenovo laptop. In both cases
they show a weird multi-stop gradient after the fix is installed. Looks
like the colour goes up-down-up-down instead of just down.

Are you sure it's differently? Look at the diff, it's supposively
exactly the same values than Yaru. Please check it and revert the status
as needed.

The proposed fix 3.30.1-2ubuntu1.18.10.1 certainly changes things, but
is equally broken as the original bug. Using the proposed fix a weird
gradient flashes up briefly that doesn't match the login screen
background and is more visually distracting than the original bug.

** Summary changed:
- Dark purple (noise) background flashes up briefly during the login animation
