I had a similar problem a couple of weeks ago! In my case, it was because I
have the 'autoread' option set by default. See
:help 'autoread'
It seems that when the window size changes, Vim tries to reread the contents
of the pipe, but those contents aren't there anymore and so you just get an
empty file. In my experience, you can prevent this specific problem with the
autocommand
autocmd BufRead /dev/fd/* setlocal noautoread
This will disable the rereading behavior only for the ephemeral "files" you
get by reading from pipes. (This works for me on macOS but you might have to
do something different on other OSes.)
Hope this helps,
Benjamin
