Почему интеграция библиотеки RmlUi не вызывает ошибок? ⇐ C++

[Anonymous]

У меня есть игровой движок C++17, который обеспечивает плавный рендеринг. В качестве графического интерфейса я интегрировал библиотеку RmlUi, и хотя она компилируется и запускается без каких-либо ошибок, она не отображается. Мое приложение использует OpenGL 4.6, GLFW3 и GLAD и работает на Linux Ubuntu 22.04. Я использую RMLUI_GL3_CUSTOM_LOADER= для интеграции с серверной частью. Я отладил приложение, и все это работает: GL-контекст, создание VAO/VBO/IBO, привязка шейдера, отправка геометрии треугольников..., RmlGL3::Initialize ОК... НО НЕТ РЕНДЕРИНГА!
Я реализовал "глубокий" регистратор для OpenGL и RmlUi, но без комментариев...
