All one has to do is avoid using CS_HREDRAW and CS_VREDRAW style flags when
creating a window.

For those of us using Win32Lib.ew, you will find the line ...

    vWindowClassStyle = {CS_HREDRAW, CS_VREDRAW }

replace this with ...

    vWindowClassStyle = {0}

and the flickering disappears.

If you want the double clicks to register for a Window you can use ...

    vWindowClassStyle = {CS_DBLCLKS}

Does this answer your concerns?

Future versions of Win32Lib will not have these as default.
