frozen panel

frozen panel was created by Jörn
Hello,

i am using Opencascade. When i add a widget for displaying Opencascade into a panel, this penal freeze and no interaction with this panel are possible.
Here is some code to reproduce the problem:
panel_2 = dockPanelManager()->addDockPanel(tr("Panel 2"), RightDockPanelArea);
panel_2->setObjectName("Panel 2");
QWidget *widget = new QWidget(0, Qt::MSWindowsOwnDC);
panel_2->setWidget(widget);

Of course, it works without Qt::MSWindowsOwnDC, but this flag is necessary for the proper work of Opencascade.

The same problem with QGLWidget:
QGLWidget *widget = new QGLWidget(); //, Qt::MSWindowsOwnDC);
panel_2->setWidget(widget);
