Increasing Size Problem When Handling WM_NCCALCSIZE

Question

Hello,

When I process the WM_NCCALCSIZE message, after minimizing and restoring the window, the window gains some size each time. I know it is caused by the function RestoreBoundsIfNecessary called in the WM_WINDOWPOSCHANGED message handler. And a solution has been provided for the issue in that stackoverflow question. But could there be a better solution? I'm waiting for your ideas. Also, this is a gif picture describing the issue.

Best wishes

A way (tested on Windows 10, 1909, .NET 4.7.2) =>

protected override void SetBoundsCore(int x, int y, int width, int height, BoundsSpecified specified)
{
    base.SetBoundsCore(RestoreBounds.Left, RestoreBounds.Top, RestoreBounds.Width, RestoreBounds.Height, BoundsSpecified.All);
}
