An Apple developer-forum report describes NSOpenGLView and window-connected framebuffers failing to render in some macOS 15.8.2 builds. Other paths, including offscreen rendering, reportedly work, so the problem cannot be generalized to all OpenGL functionality. A related kitty issue records blank windows and framebuffer errors on an M1 device even when running two versions with clean settings. These are reports limited to observed builds and applications; no announcement confirming a common cause or completed fix was found.
