multiwindow setup

[thomasgeissl]

I am having problems getting ofxFontStash to work in a multi-window setup.
It works fine, if i only use one window.
Am i doing something wrong?

Here is a little example:

#include "ofMain.h"
#include "ofxFontStash.h"

#define TWO_WINDOWS

class ofApp : public ofBaseApp{

    public:
        void setup(){
            ofSetFrameRate(60);
            _font.loadFont("OpenSans-CondLight.ttf", 100);
        }
        void draw(){
            _font.draw("lorem ipsum", 100, 100, 100);
            ofDrawRectangle(ofGetWidth()/3, ofGetHeight()/3, ofGetWidth()/3, ofGetHeight()/3);
        }
        ofxFontStash _font;
};

int main(){
#ifndef TWO_WINDOWS
    ofSetupOpenGL(1024, 768, OF_WINDOW);         // <-------- setup the GL context
    ofRunApp(new ofApp);
#endif

#ifdef TWO_WINDOWS
    ofGLFWWindowSettings mainWindowSettings;
    mainWindowSettings.setGLVersion(3, 2);
    mainWindowSettings.windowMode = OF_WINDOW;
    mainWindowSettings.monitor = 0;
    auto mainWindow = ofCreateWindow(mainWindowSettings);

    ofGLFWWindowSettings secondWindowSettings;
    secondWindowSettings.setGLVersion(3, 2);
    secondWindowSettings.windowMode = OF_WINDOW;
    secondWindowSettings.monitor = 0;
    secondWindowSettings.shareContextWith = mainWindow;
    auto secondWindow = ofCreateWindow(secondWindowSettings);


    auto mainAppPtr = std::make_shared <ofApp>();
    auto secondAppPtr = std::make_shared <ofApp>();

    ofRunApp(mainWindow, mainAppPtr);
    ofRunApp(secondWindow, secondAppPtr);

    ofRunMainLoop();
#endif
}
