Проблема с фальшивыми множественными вертикальными событиями касания одновременно - OpenJDK 11.0.2

0 голосов
/ 06 марта 2019

Несколько раз в день я наблюдаю несколько событий касания одновременно, тогда как я касаюсь только одним пальцем в одном месте.

Эти касания всегда вертикальные = почти одинаковая X-координация, но большая площадь в Y-координации. Я использую разрешение 1920x1080.

Я пробовал 2 разных сенсорных монитора, но одинаковое поведение - оба iiyama T2235MSC-B1. Я написал сенсорное приложение на C ++, чтобы проверить мой сенсорный экран, но в C ++ все нормально, такого поведения нет. Только в Java FX. Я использую OpenJDK 11.0.2 и Windows 10.

Каждый раз, когда это происходит, только когда я касаюсь экрана. Есть ли в JavaFX кэш для событий касания, который не очищен должным образом? Вы тоже это наблюдали? Что я могу сделать? Это showtopper для всего моего приложения в производстве.

Проблема начинается с

...

Многие другие события происходят один за другим, приблизительно до 8 стационарных событий в один:

EDIT:

Я хотел бы добавить, что я использую этот код для привязки EventHandler: 

getScene().setOnTouchPressed(this);
getScene().setOnTouchReleased(this);

Тогда этот метод называется: 

@Override
public void handle(InputEvent e) {
    handleEvent(e);
}
private void handleEvent(InputEvent e) {…}

Точка касания повторяется (для регистрации) следующим образом: 

if (e instanceof TouchEvent) {
TouchEvent te = ((TouchEvent) e);
INPUT_EVENTS_LOGGER.debug("- touchEvent - setID = " + te.getEventSetId() + ", touchPoint count = " + te.getTouchCount() + ", point = [" + te.getTouchPoint().getScreenX() + ", " + te.getTouchPoint().getScreenY() + "]");
for (TouchPoint tp : te.getTouchPoints()) {
INPUT_EVENTS_LOGGER.debug("--> point: [" + tp.getScreenX() + ", " + tp.getScreenY() + "], state = " + tp.getState().name());
}
}
