spinner fills console with WWWW in JetBrains console.

As I started spinner in Goland, spinner fills console with WWWW.

But if I started command from iTerm, the problem no longer appears.

Same issue, problem exists for standard Windows terminal since v1.12.0. Rollback to v1.11.1 helps. For macOS iTerm - no problems.

Hmmm, I wonder what the possible commonality between the Goland terminal and the Windows terminal is? I'll checkout a differ between the two releases to see if I see anything obvious. Thanks for reporting this.

same problem on windows putty terminal. I also rollback to v1.11.1 and resolved.

Any update on this?

Just encountered this on Linux with zsh shell. But only for one line that was longer than my terminal width and had to be wrapped around.

Here's the root cause:

spinner/spinner.go

Lines 399 to 401 in 2cb1a33

	for _, c := range []string{"\b", "\127", "\b", "\033[K"} { // "\033[K" for macOS Terminal
	fmt.Fprint(s.Writer, strings.Repeat(c, n))
	}

I tried removing this code and it still works fine on macOS iterm2, Terminal, JetBrains terminal and vscode's terminal. I'm not sure what this compatibility is for, maybe a historical reason?

Thanks @Dreamacro . Would it be possible to open a pull request?
