<h3 dir="auto">To Reproduce</h3>
<ul dir="auto">
<li>Open an Electron app (occurs in the latest versions of Slack and VSCode)</li>
<li>Move it to the other monitor by dragging with the mouse and let it snap to fullscreen OR move to other monitor with <code class="notranslate">Windows + Left</code> key and then <code class="notranslate">Windows + Up</code></li>
</ul>
<h3 dir="auto">Workaround</h3>
<p dir="auto">Press the <code class="notranslate">Windows + Left</code> or <code class="notranslate">Windows + Right</code> key to display the app in only half of the screen<br>
OR<br>
Keep the app windowed and drag it to an "almost fullscreen" size</p>
<p dir="auto">NOTE: I previously reported this at <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="525837314" data-permission-text="Title is private" data-url="https://github.com/electron/electron/issues/21229" data-hovercard-type="issue" data-hovercard-url="/electron/electron/issues/21229/hovercard" href="https://github.com/electron/electron/issues/21229">#21229</a> which was closed after someone was unable to reproduce it. I insist that this bug <em>is</em> present, and <em>is</em> an Electron bug, because it occurs on Caprine, Slack, WhatsApp, VS Code, and my own home-built Google Photos desktop app. After the issue was closed, <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/nielsvandepas/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/nielsvandepas">@nielsvandepas</a> was able to reproduce the bug, but the issue was not reopened after commented. I'm not sure why this issue couldn't be reproduced using the steps I've given, so I'm attaching screenshots. Sorry for duplicate - I don't have permissions for reopening the other issue.</p>
