Graphics / Position and Size off under macOS 10.14 Beta

« on: July 17, 2018, 09:07:14 am »

Hello,

while testing macOS 10.14 Beta I discovered a bug which appears in combination with SFML.
Under macOS 10.14 all positions and sizes in the window are wrong but under macOS 10.13 everything works as expected.

I have made some examples:

200x200 Window, 100 radius circle at 0,0

(click to show/hide)

#include <SFML/Graphics.hpp>

int main() {
    sf::RenderWindow wnd(sf::VideoMode(200, 200), "Test");

    sf::CircleShape circle(100.0f);
    circle.setFillColor(sf::Color::Green);

    while(wnd.isOpen()) {
        sf::Event evt{};
        while(wnd.pollEvent(evt)) {
            if(evt.type == sf::Event::Closed) {
                wnd.close();
            }
        }

        wnd.clear(sf::Color::Black);
        wnd.draw(circle);
        wnd.display();
    }

    return 0;
}

macOS 10.14:


macOS 10.13:

200x200 Window, 100 radius circle at 50,50

(click to show/hide)

#include <SFML/Graphics.hpp>

int main() {
    sf::RenderWindow wnd(sf::VideoMode(200, 200), "Test");

    sf::CircleShape circle(100.0f);
    circle.setFillColor(sf::Color::Green);
    circle.setPosition(50, 50);

    while(wnd.isOpen()) {
        sf::Event evt{};
        while(wnd.pollEvent(evt)) {
            if(evt.type == sf::Event::Closed) {
                wnd.close();
            }
        }

        wnd.clear(sf::Color::Black);
        wnd.draw(circle);
        wnd.display();
    }

    return 0;
}

macOS 10.14:


macOS 10.13:

It looks like SFML use internally only 100x100 size while the window is 200x200, maybe the viewport is generated wrong.

All projects are generated with:

cmake -DCMAKE_OSX_DEPLOYMENT_TARGET=10.13

generating with

cmake -DCMAKE_OSX_DEPLOYMENT_TARGET=10.14

doesn't change anything (also tried other different versions).

SFML is installed from 2.5.0 source with:

cmake
make
sudo make install

Apple Clang Version is 10.0.0 (cland-1000.10.38)

Edit: Change the scaling of the display changes nothing
