<li>Operating system: Windows 10 64-bit</li>

<p dir="auto">Can't upload a screenshot right now. Steps to reproduce:</p>
<ol dir="auto">
<li>Create a frameless browser window</li>
<li>Set your windows taskbar location to be at top of screen</li>
<li>Maximize the window</li>
</ol>
<p dir="auto">You'll be able to see the effect I'm describing. If you move the window it becomes more apparent</p>
<ul dir="auto">
<li>Electron version: <code class="notranslate">0.37.4</code></li>
<li>Operating system: Windows</li>
</ul>
<p dir="auto">When I maximize my <a href="https://github.com/electron/electron/blob/master/docs/api/frameless-window.md">frameless</a> electron window a small part of the window in an unmaximized state is visible on a secondary monitor.</p>

<p dir="auto">You can visibly see the "line between the monitors" and you can see some really strange overhanging content that is over that line.</p>
<p dir="auto"><strong>Steps to reproduce</strong></p>
<ol dir="auto">
<li>Open an electron app</li>
<li>Maximize the app on your secondary display</li>
<li>Look closely for the overflow onto your primary display</li>
</ol>
<p dir="auto">This might take a few times to trigger, it appears to do it about 70% of the time <g-emoji class="g-emoji" alias="confused" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/1f615.png">😕</g-emoji></p>
