New lines do not start from column 0

Hi.
Thanks for creating this crate.

Can you please tell me if I am doing something wrong or there is a bug?
I made a minimal repro at https://gitlab.com/yerke/repro_tui_bug
The problem is that new lines do not start from column 0.
Here is the example of the output I see on Mac:

$ ./run.sh 
    Finished dev [unoptimized + debuginfo] target(s) in 0.02s
     Running `target/debug/repro_tui_bug`
Hello, world!

                                                                   [2019-10-27T03:52:26Z DEBUG repro_tui_bug] Hello from main thread 2
                                                      [2019-10-27T03:52:33Z DEBUG repro_tui_bug] Please press any button
[src/main.rs:12] key = Ok(
    Char(
        'f',
    ),
)
[2019-10-27T03:52:33Z DEBUG repro_tui_bug] Hello from spawned thread 1
[2019-10-27T03:52:33Z DEBUG repro_tui_bug] Hello from spawned thread 2
$ 

Thanks.

Start by reviewing the minimal reproduction at https://gitlab.com/yerke/repro_tui_bug and run its run.sh script to reproduce the indentation on macOS. Use src/main.rs:12 and the logged output as entry points, then trace the console rendering behavior. Done means newly emitted lines begin at column 0 without breaking the shown output.
