QOpenGLFramebufferObject not working since 5.4

glararan

Hi,

All my FBOs stops working on Qt 5.4, I did migration from QGLWidget to QOpenGLWidget

I did this code with fbo and QOpenGLWidget went blue.
@for(int tx = 0; tx < TILES; ++tx)
{
for(int ty = 0; ty < TILES; ++ty)
{
if(tileLoaded(tx, ty))
{
qDebug() << fbo->bind(); // true

            GLfuncs->glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
            GLfuncs->glViewport(0, 0, fbo->width(), fbo->height());

            tile[x][y]->draw(...);

            qDebug() << fbo->release(); // true

            GLfuncs->glViewport(0, 0, viewportSize.width(), viewportSize.height());
        }
    }
}

QImage img = fbo->toImage();

qDebug() << img.width() << img.height(); // 8K

img.save("test2.png");@

Everything worked on 5.3. There is something new thing I missing to do, but what?

Thanks,

Regards, glararan.
