Dialog glitch with pancurses backend on Alacritty

[HenryTheCat]

I am reporting a bug. Specifically, it's a graphical glitch that happens only under specific conditions.

Problem description

The border of the dialog view will render incorrectly and produce glitches at the end of the line.

    siv.add_layer(
        Dialog::new()
            .title("A dialog")
            .content(TextView::new_with_content(TextContent::new(
                "Some text"
            )))
            .button("Back", |s| {
                let _ = s.pop_layer();
            }),
    )

Environment

• Operating system: macOS
• Backend used: pancurses (seems to work fine with the other ones)
• Virtual terminal: Alacritty 0.4.2 (seems to work fine with Terminal.app and iTerm)
• Current locale: en_GB.UTF-8
• Cursive version: 0.14 (from crates.io)

Thanks for the report! Will investigate.

Arf cannot reproduce here - it works fine locally, using current cursive master and current alacritty git master:

% alacritty --version
alacritty 0.5.0-dev (f48c43f4)

Also tried it with alacritty 0.4.2, same result.

Might be a macOS-specific issue? Are you sure your locale is valid? (It's a common issue).
Can you post a screenshot of the issue?

Here it is:

I also found out it doesn't happen when I run it from inside tmux.

PS: the '#' shold have been printed in a different position, approximately under the dialog on the right.

Woo it does look pretty messed up.
Does it happen with every example from the repo?
What is your $TERM env variable?

I tested a few, and all of them have issues:

What is your $TERM env variable?

Do you know if it only affects the pancurses backend?

[HenryTheCat]

pancurses and ncurses, it appears; termion, crossterm and bearlibterminal works fine.
