Hi, We have a crash in OSG in the following setup : - Microsoft Surface Pro 4 with Windows 10. - Application is displayed on a deported screen using a Display link adapter (Main screen is off).
Crash happens in the module osg130_osg 0:006> # Call Site 00 osg130_osg!osg::GLBufferObject::GLBufferObject 01 osg130_osg!osg::GLBufferObjectSet::takeOrGenerate 02 osg130_osg!osg::GLBufferObjectManager::generateGLBufferObject 03 osg130_osg!osg::GLBufferObject::createGLBufferObject 04 osg130_osg!osg::BufferObject::getOrCreateGLBufferObject 05 osg130_osg!osg::DrawElementsUShort::draw 06 osgdb_osgearth_engine_mp 07 osgdb_osgearth_engine_mp 08 osg130_osgutil!osgUtil::RenderLeaf::render 09 osg130_osgutil!osgUtil::RenderBin::drawImplementation 0a osg130_osgutil!osgUtil::RenderBin::draw 0b osg130_osgutil!osgUtil::RenderBin::drawImplementation 0c osg130_osgutil!osgUtil::RenderStage::drawImplementation 0d osg130_osgutil!osgUtil::RenderBin::draw 0e osg130_osgutil!osgUtil::RenderStage::drawInner 0f osg130_osgutil!osgUtil::RenderStage::draw 10 osg130_osgutil!osgUtil::SceneView::draw 11 osg130_osgviewer!osgViewer::Renderer::draw 12 osg130_osg!osg::GraphicsContext::runOperations 13 osg130_osg!osg::OperationThread::run 14 osg130_osg!osg::GraphicsThread::run 15 ot20_openthreads!OpenThreads::SetProcessorAffinityOfCurrentThread 16 ucrtbase!invoke_thread_procedure 17 ucrtbase!thread_start<unsigned int (__cdecl*)(void * __ptr64)> 18 kernel32 !BaseThreadInitThunk We get these error messages : Windows Error #127: [Screen #0] ChooseMatchingPixelFormat() - wglChoosePixelFormatARB extension not found, trying GDI.
