This is interesting; I am just a user, working on a Vulkan engine,
and resizing doesn't look good here: mostly, during resizing the
system is so busy with trying to keep up that the window looks empty
until you stop moving the mouse.

Can you explain to me in simply English what is the idea behind
what you are doing that makes resize more smooth?
