Я пытаюсь запустить все оконные приложения с компьютера и вывести их список. Когда пользователь нажимает на элемент списка, я хочу сделать скриншот содержимого этого приложения. В настоящее время этот код работает в не трехмерных приложениях, таких как консоли, визуальный код и случайные частичные окна. Как заставить это работать на 3D-приложениях, таких как Roblox?
