This past week or two I've noticed that this issue is solved! I have apt
upgrades automatically scheduled every so often, so I imagine there was
a kernel release that fixed this issue. Thanks for the cooperation!
** Changed in: linux (Ubuntu)

Latest kernel release still doesn't fix the issue - machine is still
pretty unusable when flickering.

I’ve also had some issues with the audio, but I’ve been able to fix that up
by fiddling with pulseaudio.
Re the bug fix, should I try a clean install? This isn’t optimal since I’m
mostly set up now, but would this help the bug fix take effect?

In the past "ice-lake-flicker" issues have been related to the audio
system(!). That was supposedly fixed in bug 1875254, but your log shows
some errors in the same area:
[ 117.852074] sof-audio-pci :00:1f.3: error: no reply expected, received
0x0
[ 117.944970] sof-audio-pci :00:1f.3:
I’ve also had this thought. I’ve tried this, but the flickering will start
before then, usually during the startup splash and login screen. Makes me
think that you’re right about it being a kernel bug

Maybe try selecting 'Ubuntu on Wayland' from the login screen (icon in
the bottom right corner after you select the user). That will use a
different render path and might avoid the problem.

I've tried 5.7 and the problem seems to persist - weird, since I thought
that Kernel supported through TIger Lake and this machine runs an Ice Lake.

It's *probably* a kernel bug and probably already fixed in a newer
kernel. So you might want to try one of those:

Yep - I’ve tried removing nomodeset after this update but it hasn’t seemed
to take away the flickering, leaving it on for the time being until the bug
is fixed.

Maybe bug 1875254 fixed it? Try updating to get that fix:
sudo apt update
sudo apt full-upgrade
Reboot

Removing nomodeset reverts back to the original screen flickering problem
with almost zero usability. Are there any other solutions to this?

"nomodeset" will disable all hardware graphics support so it will use
high CPU and likely cause screen tearing. That's not really a solution
so you should remove "nomodeset" as soon as you can.
