ResizableWindow::setResizable() cause blinking

Hello. I am using ResizableWindow Class.
When window is present, I call
resizableWindow->setResizable(true/false, true);
as result, entire window is re-created with expected style, but with visible blinking.
On Mac blinking doesn’t visible.
Is it possible change window style without re-creating?
Or “freeze” part of screen until correct window re-drawing is happen?
