[Interest] Flickering when resizing QOpenGLWidget on macOS

[Patrick Stinson]

It seems that QOpenGLWidget doesn’t keep up with its parent layout when resized. It flickers with a black gap, which causes very jitter behavior when child widgets are layed out within it. Is there any way to fix or work around this? See attached video (sorry for shading in second half).
