Hi, I have an application which has custom OpenGL rendering through a QQuickFramebufferObject and corresponding Renderer in a Qt Quick Window.
Now, I need to open a second window which should use the same mechanism to render the scene from a different viewpoint. This works nicely on MacOS, but fails with a white window on Windows 11. I get a GL_INVALID_OPERATION_ERROR when trying to bind an FBO from the second window which was created in the first. I was thinking that there might be some differences in how MacOS and Windows handle context sharing, but I have tried setting a global shared context using the Qt::AA_ShareOpenGLContexts flag, and I have also tried creating my own share context. I have verified that the current context in each window has the same share context, but none of this seems to have any effect. This is on Qt 6.6.2 Any ideas?
