No. If the app uses termcap/terminfo in a portable manner, this should
not be a problem. But: a common mistake is to lie about the terminal in
use. For instance if an app does run on ANSI terminals only it's useless
to "export TERM=ANSI" while using an xterm.

There is an overhead but it is usually under 5% depending how many
system calls the app uses. You have to trace the app to find out what
is going wrong.

Depends on the app. I know people who used to run production systems
with linux abi. Linux abi is not complete, maybe something is missing
for your app. If you like to contribute, find out what is missing or
going wrong. A good point to start is to trace your app.
