* What led up to the situation? Installed Debian Buster/Sid with Cinnamon 3.6.7-8
* What exactly did you do (or not do) that was effective (or ineffective)? Switching themes.
* What was the outcome of this action? If you switch between different "window borders" in the theme settings, you will find that in some themes (for example in Default, Greybird, Menta, BlueMenta ...) in some dialog boxes the close button at the top right of the dialog is missing! The theme Bluebird contains the Close button. See also the two attached screenshots to illustrate the problem.
Modal windows don't show a close button, that's just the way things are. Modal windows should show a Close or YES/NO button at the bottom.
Also, gtk apps could use client side decorations which override the window manager settings, so you might be seeing some windows that are designed no to show a titlebar with buttons in it.
If you are really annoyed by this you might want to try giving gtk3-nocsd, but personally I consider gtk3-nocsd a hack.
In any case this doesn't look like cinnamon bug but a gtk3 behavior. Happy hacking, -- Saludos, /\/\ /\ >< `/
