Description

        if (MyGraphicDriver->IsDeviceLost())
        {
          MyViewManager->ReComputeStructures();
          MyGraphicDriver->ResetDeviceLostFlag();
        }

Current implementation is unable to restore presentation for connected structures which are not displayed as independent presentations.
