Re: [Interest] Issues with QPainter on Mac 10.10

Because you cannot actually call any QT function based on OpenGL 3.0 anymore without letting the application crash (e.g. renderText in QGLWindow) , when selecting a 4.1 context (only under mac osx). But I agree that it is a pain to propose implementations for every OpenGL core versions only because Apple does not provide a compatibility profile. Thanks for the link. In fact I was not proposing calling those functions, rather something like QImage image(size, format); QPainter p(image); p.drawText(); /* etc.etc. */ p.end(); QOpenGLTexture *texture = new QOpenGLTexture(image); /* bind, use it */ -- Giuseppe D'Angelo ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Unfortunately it's a known bug which has been deemed out to scope to fix: https://bugreports.qt.io/browse/QTBUG-33535 Your best workaround is painting on a QImage instead, loading it on a texture (QOpenGLTexture) and then drawing a quad.
