This is a very tricky issue, and it is caused by this piece of code.

protected override void WndProc(ref Message m) {
    // https://rjcodeadvance.com/final-modern-ui-aero-snap-window-resizing-sliding-menu-c-winforms/
    const int WM_NCCALCSIZE = 0x0083; // Standar Title Bar - Snap Window
    if (m.Msg == WM_NCCALCSIZE && m.WParam.ToInt32() == 1) { // Remove border and keep snap window
        return;
    }
}

I have two monitors. The problem exists on the main monitor, while the second monitor is fine. So, I think this is a bug in Windows itself. The taskbar is a system-level UI, and it should be on top. It’s strange that it gets covered by windows.

It seems like a lot of projects have encountered this issue, for example this fix: https://github.com/electron/electron/pull/25217
