  "message": "[Linux] Synchronize multi-window renderer lifetime across GTK and raster threads\n\nWhen destroying an active secondary window on Linux:\n\n1. FlView did not retain a strong reference to self-\u003erenderer, allowing gtk_container_dispose() on self-\u003eevent_box to unreference and free self-\u003erenderer during dispose() while the Flutter raster thread may still call fl_view_present_layers(self-\u003erenderer). Retain a strong reference to self-\u003erenderer until fl_view_finalize().\n\n2. FlViewRendererOpenGL and FlViewRendererSubsurface destroyed frame_mutex and task_runner in dispose() while leaving compositor and frame for finalize(). Move task_runner and frame_mutex cleanup to finalize() so present_layers() can safely access them after dispose().\n\n3. Synchronize compositor, frame, and render_context teardown under frame_mutex in cleanup_opengl_resources() during unrealize() and dispose() on the GTK main thread. Only clear the GTK thread\u0027s current GdkGLContext if this window\u0027s render_context is the one currently bound.\n",
