I believe the issue is from a change in the osgViewer Library in GraphicsWindow32.cpp. In GraphicsWindowWin32::init() The following check has been added since the 3.2.1 version: int windowX = 0, windowY = 0, windowWidth = 0, windowHeight = 0; if (_traits.valid()) { windowX = _traits->x; windowY = _traits->y; windowWidth = _traits->width; windowHeight = _traits->height; } if (areWindowDimensionsChanged(_hwnd, _screenOriginX, _screenOriginY, windowX, windowY, windowWidth, windowHeight)) { resized(windowX, windowY, windowWidth, windowHeight); } In cases where the window has been created outside of osg and the window handle is added to the graphics context as in the osgViewerMFC application, the check in areWindowDimensionsChanged() will always be true since it is assuming that the window passed in via _traits is in the overall screenspace and not relative to the view. When resized() is called with the updated window the graphics window is offset from the previously created window. I believe if Rain moves his osgViewerMFC application window to the upper left corner of the screenspace he will see something like the view below where the view is offset from the intended window. <Image removed> ============================ I implemented the following change which corrects the issue for my applications as well as the osgViewerMFC in GraphicsWindow32.cpp. bool checkchange = false; int windowX = 0, windowY = 0, windowWidth = 0, windowHeight = 0; if (_traits.valid()) { checkchange = (_traits->x != 0) || (_traits->y != 0); if (checkchange) { windowX = _traits->x; windowY = _traits->y; windowWidth = _traits->width; windowHeight = _traits->height; } } else checkchange = true; if (checkchange) { if (areWindowDimensionsChanged(_hwnd, _screenOriginX, _screenOriginY, windowX, windowY, windowWidth, windowHeight)) { resized(windowX, windowY, windowWidth, windowHeight); } } I believe this preserves the intent of the added check which works correctly when the process uses GraphicsWindowWin32::createWindow() to create the graphics window. I have attached the modified GrahicsWindowWin32.cpp file for consideration.
