If a terminal declaration is improper, it is likely to be suboptimal.
A terminal emulator should ideally have its own, adequate terminfo entry.

When such things happen, either the terminfo description is improper, or
the application has bugs with terminal handling.  One should either correct
the terminfo description, or debug the program.  We probably agree on the
fact these areas are not that much fun, and diagnosing terminfo-related
problems require patience, study, and some dedication :-).

So true! :-)
