You closed this yourself. Did you find the cause of the problem?

There was an issue similar to this one: #66. Are they related?

It works fine when I set LC_CTYPE="en_US.UTF-8". and LC_CTYPE="zh_CN.UTF-8" was make horizontal border wrong. I found the solution from gdamore/tcell#203 .

Copy from gdamore/tcell#203

Another solution, you can force runewidth to return 1 for normal symbols, like '-':

import "github.com/mattn/go-runewidth"

func main() {
    runewidth.DefaultCondition.EastAsianWidth = false
}

Other unicode word will still be 2, like '中'.
