У меня возникают серьезные проблемы с производительностью и зависание пользовательского интерфейса в моем приложении JavaFX при навигации по страницам в виде галереи.
Я запускаю это на AMD Ryzen со встроенной графикой.
Несмотря на использование задачи для фоновой загрузки, я наблюдаю значительное зависание и увеличение объема памяти. Вот логи моей консоли во время навигации:
PPSRenderer: scenario.effect - createShader: LinearConvolveShadow_4
Search: test
