Каким образом перемещать FramelessWindow?

Question

Столкнулся с проблемой: при перемещении окна через mousePressEvent и mouseMoveEvent возникает вот такая ситуация:

При нажатии на виджет (в данном случае кнопка) и ведении мышки в сторону при попадании на "тело" окна окно дёргается.

Подскажите как еще можно реализовать перемещении FramelessWindow окна?
Или же как можно устранить данную проблему?

Я не думаю, что вы собираетесь перетаскивать окно при нажатии на кнопку.

Как вариант, попробуйте. Обратите внимание на объект self.pressing.
