Я сделал простую игру, используя Python и Kivy. Однажды, когда я запустил код, у меня возникла проблема с дублированием графики. В основном каждый объект на экране появляется несколько раз (как если бы он рисовал все объекты на экране снова и снова). Программа раньше работала нормально, но однажды эта проблема только начала возникать.
Я попытался запустить тот же код на компьютере друзей, и он работает нормально, так что это может быть связано с оборудованием. (У меня Alienware 17 r4 и у него есть Macbook) Предыдущие версии моего кода, у которых не было проблемы, теперь имеют ее.
Редактировать: я думаю, что проблема связана с тем, что не работает clear canvasдолжным образом. Я нашел вопрос, который, по-моему, описывает ту же проблему:
Kivy canvas.clear () не очищает холст
Однако на этот вопрос не было ответа. Изменение размера экрана вручную приводит к исчезновению проблемы, как упоминалось в связанном вопросе
