On macOS, using a high resolution monitor like the built-in screen, text rendering is incorrect

[vtbassmatt]

On my Mac (which has a non-high-DPI monitor attached), if I run an rltk app from a terminal on the laptop screen, I get super-tiny font rendering in the wrong place. If I drag the terminal over to the external monitor and then launch the app, everything looks fine.

Laptop screen:

External monitor:

The code is chapter 1 of the book:

rltk::add_wasm_support!();
use rltk::{Rltk, GameState, Console};

struct State {}
impl GameState for State {
    fn tick(&mut self, ctx : &mut Rltk) {
        ctx.cls();
        ctx.print(1, 1, "Hello Rust World!");
    }
}

fn main() {
    let context = Rltk::init_simple8x8(80, 50, "Hello Rust World", "resources");
    let gs = State{ };
    rltk::main_loop(context, gs);
}

I'm having the same issue. Additionally if I resize the window on my laptop screen the rendering corrects itself.

Actually, now I'm trying it with no monitor attached, and I still get the incorrect rendering on the laptop screen. Updating title.

Like @cpv it fixes the rendering if I tweak the size of the window.

I have the same issue, Rltk 0.5.17, Macbook Pro. On the laptop screen (retina) the text renders to the bottom left 25% of the window:

Same as @cpv, tweak the size of the window and it's fixed. Same regardless of whether an external monitor is attached or not. After tweaking the size:

Same on windows laptop with 4K screen (build-in). After resize everything looks good.
