Hello, I am getting the following error in an OSG viewer, with a osgViewer::GraphisWindowEmbedded into a QOpenGLWidget:
detected OpenGL error 'invalid operation' after applying attribute Viewport 0x7f93fbe97170 I get this error every time I call QOpenGLWidget::update(). This happens only under MacOS X (I have Qt 5.7 and OSG 3.4). This does not happen under Linux. I know this is insufficient information for any debug. But how can I get more details to debug this?
