What file would I have to edit to remove the round corners?
(I'm quite sure it isn't in cinnamon.css.)
Thanks in advance.

That's going to depend on the theme you are using. But it's style by the gtk theme so it will be in your themes gtk-3.0 folder.

Thank you.
In my theme's directory, I see two Gtk-3x subdirectories.
Both .css files are tiny with nothing related to corner radius.

What theme is it? It's distributing it's css as a gresource file so can't be directly edited.

Edit - it's OK - from here I remember you are using Adapta installed via a deb file - viewtopic.php?p=1636237#p16362370

Solution - use the Cinnamon Spices version of Adapta which provides the css in a non-obfuscated format.

Thank you for the tip!
I'll check it out.

Sorry to bother you.
I tried Adapta from Spices and I replaced all border-radius: 2px with border-radius: 0px in cinnamon.css and both instances of gtk.css.
The rounded corners of the popups are still there.
Could it be that it's hard-coded?

Did you switch themes after making those changes? Or alternatively logged out and back in? For your changes won't affect running processes otherwise.

Yes. Just to be sure I even rebooted.

Ok, I had a look. Here's your problem: https://github.com/linuxmint/cinnamon-s ... n.css#L100 (it's an .svg graphic, not a border-radius)

Fantastic! Thank you VERY much.

It wasn't the svg file.
I changed Themes/Controls and now it's perfect
