Original GitHub issue: https://github.com/asciinema/asciinema/issues/73

I am using the following code in my prompt, which results in $rprompt being right aligned:

PR_FILLBAR="%f${(l:(($TERMWIDTH - ( ($rprompt_len + $prompt_len) % $TERMWIDTH))):: :)}"
…
PROMPT="${prompt}${PR_FILLBAR}${rprompt}

With a maximized terminal window however, asciinema appears to not get the width of the window correct, where $rprompt is being cut off.

See the following screencast: https://asciinema.org/a/13845

Where does the $TERMWIDTH var come from? Is it initially set by terminal emulator or by shell?

It's derived from $COLUMNS:

local -h TERMWIDTH=$((${COLUMNS}-1))

Is this problem happening only during playback or it's already there when recording?

Please try the latest version and let me know if that's still the case.
