Black screen and normal screen using QOpenGLContext + QQuickWindow

[BrunoGSA]

When I use QOpenglContext with QQuickWindow, the screen gets dark for a frame e gets normal render (opengl partial view + QT Controls). Is there anything I am missing? I call swapBuffer and after that I call makeCurrent.
I saw everything is only one thread.
When I initialize the app I also call makeCurrent.

Can anybody help me?
