<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I don't see how.
It's no different to when the mouse is actually over the containment.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The case for when you're in the 4px margin at the edge of the panel seems like it must be tiny.</p></pre>

Every postEvent is expensive, not for allocating memory, case event is append to queque. Here problem is simple - QEvent::Leave is append to queque <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">before</em> MouseMove, this behavior can be easy preproduce at slower CPU's like mine. To make redirect on evey mousemove is not only stupid, it's more expencive than any other event.</p></pre>

But for me it's better break this except everything else :)</p></pre>
