I’ve dig into jogl swap buffers implementation on macOS, it seems that VSync is disabled deliberately for 10 frames when resizing, maybe flickering is a side effect.

My experiments shows that the flickering is actually when you don’t paint the window in time, and at which point macOS composers shows default color. But that time may happen after swap buffers, making previous VSync’ed paint in vain.

Just guess.
