after running mtr, my terminal size changes

[lilydjwg]

Actual command ran is /usr/bin/grc -es --colour=auto mtr github.com, which is an alias of mtr after an update.

It runs mtr in a somewhat 80x24 sized space instead of what my terminal actually is, and after I exit, there are some strange things like when the cursor is at the last line, it doesn't scroll (only the last line updates), after Ctrl-L, my cursor can't go down after 24 lines or so (it scrolls).

After running reset, vim or htop, it restores to normal.

I'm on Arch Linux and grc is of version 1.11.1-2.

i discovered the same behaviour that running grc breaks a interactive tty in docker. LINES and COLUMNS are not set correctly and the tty breaks inside docker.
