Изменчивое воспроизведение видео (Просмотр веб-страниц и в игре)

Подошла нечетная видео проблема производительности. Я получаю регулярное изменчивое воспроизведение видео. Довольно трудно для объяснения, но я приложу все усилия.

При выполнении любого действия (как прокрутка в веб-браузере, воспроизведение видео (gif/jif), игры (Переживающий Марс через Пар), катастрофические отказы VLC, и т.д.) мои экраны 'приостановятся' в течение одной десятой секунды как он, отбрасывает кадры и затем возобновляется. Повторения каждую секунду к двум секундам. Причуда - то, что 2D/3D рендеринг, если не 'икая' является пятном на и потрясающий.

Это - новая установка 16.04 и в течение недели к 18,04 вскоре после того, как 18.04 вышел.

Я уже обновил все свое программное обеспечение (насколько я знаю), перезагрузил. 4.15.0-20-универсальное выполнение. В чем других сведениях Вы все нуждаетесь?
