We run into a problem with an AMD Radeon RX 6800 graphics card when shutting down our application. When we call Unigine::Engine::init with our own created opengl context the next call to "wglDeleteContext(m_context);" crashes in the graphics driver. When we are not calling Unigine::Engine::init we are able to destroy the opengl context normally. This happens with Qt Opengl Context and build from scratch Windows OpenGL context. We don't know what is happening in the init call with te opengl context, but maybe you can tell us? NVidia graphics cards work. Thanks.

Hi, we currently try to use the unigine render context to render a external symbology to a texture within the same graphics context. To achive this we need to get the current context of the Unigine Render engine. We've tried to use the Unigine::RenderContext class by getting it from the App like this. App::get()->getGLContext() We've been also able to get the ogengl name of that context and the void* returned is not null. We currently have trouble interpreting the return value, as there is no further information. In a current setup that we use, we use glfw in the backend that allows to access the native contexts via the following methods for Linux and Windows. The methods glfwGetGLXContext and glfwGetWGLContext described here https://www.glfw.org/docs/latest/group__native.html define the interface that we currently would expect. Is there already something in Unigine that we could use to access the native OS's rendering context? Best regards Florian

Hello everybody, we are planning a Project now with Qt Ui Elements on top of a Unigine Widget. We made a little research and found out that Qt is using a BackingStore to composite their UI Elements/Widgets (Labels, Buttons etc.). After calling winId() on a QWidget, the QWidget class creates a native HWND on Windows. When creating a OpenGL context with the HWND the rendered content is not blended correctly with the UI. Since Unigine uses the same technique with their AppQt example, we are wondering if you have any idea, how to do this. Or is there a solution to use a QOpenGLWidget instead of a QWidget? Thanks, Sebastian
