I did not, thank you. My email client was just murdered by Slack so
I’m getting used to a new one...

Oh, I didn’t know about this. I like it, but it doesn’t fix the issue.
It does make it seem like whatever is rendered on the edges is just
lightened, as it lightened my modeline:

It’s different on my theme. My guess is that this is a new default
window behavior to give windows a more 3d appearance. I do not know
how to opt out of it yet. Hopefully the iTerm maintainer gets back to
me.

Sorry, I should have clarified, the screenshots were of night-owl,
which I’m using. I only specified manoj-dark in the repro because it
is built-in.
