    Qt documentation for QOffscreenSurface:

    

    Due to the fact that QOffscreenSurface is backed by a QWindow on some

    platforms, cross-platform applications must ensure that create() is only

    called on the main (GUI) thread. The QOffscreenSurface is then safe to

    be used with makeCurrent() on other threads, but the initialization and

    destruction must always happen on the main (GUI) thread.
