Any feedback?
More information after debug:
The issue comes from the QGLWidget. I have two views, one is developed with QWidget and another is developed QGLWidget. They works fine with QTitanRibbon 4.18.0, and after upgrade to 5.0.0, the QGLWidget view always overlap the QWidget view.
any support is appreciated.

Thank you for the bug-report. Bug has been reproduced. Note, QGLWidget it is deprecated class. The best way to use QOpenGLWidget instead.

if for some reason you cannot use it now, then just comment out the line in the constructor of WindowTitleBar class:

WindowTitleBar::WindowTitleBar(QWidget* window)
: QObject(window), m_p(Q_NULL)
{
Q_ASSERT(window != Q_NULL && window->isTopLevel());
//qApp->setAttribute(Qt::AA_DontCreateNativeWidgetSiblings); //Comment this line
