Valgrind сообщает о множестве ошибок при запуске программы opengl на ATI. Стоит ли мне беспокоиться?

У меня очень сложное приложение OpenGL, работающее на встроенном устройстве с графическим чипом ATI, работающее под управлением RT Linux. Часть приложения протестирована с юнит-тестами. Все они проходят, и нет сообщений об утечке памяти или неправильном доступе. Тем не менее, приложение имеет некоторые причуды, а некоторые вещи не ведут себя хорошо.

Сегодня я попытался запустить это приложение, используя valgrind, и во время инициализации я вижу некоторые недопустимые операции чтения / записи в память, все они связаны с драйвером ATI:

Мне хорошо известно, что эти операции чтения / записи не определены и что ATI имеет репутацию плохих драйверов для Linux.

Вопрос в том, стоит ли мне беспокоиться об этих ошибках? Я знаю, что valgrind иногда сообщает о ложных проблемах.
