I haven't found this report yet by searching in this site for pinentry ncurses and pinetry ncurses size.
When I ask pass for a password, e.g. via pass -c path/to/password, it invokes gpg to decript a file from the password store, so gpg asks for the passphrase of the associated key. If one selects the <cancel> button and presses enter, he gets the error gpg: decryption failed: No secret key. This is imho a bit strange, but ok.
However, and here lies a bug (or at least a perceived bug), if the terminal window is too small, that error is displayed directly, without even opening the ncurses dialog box.
For a screencast of the strange behavior, please refer to my question here.
