<h1 dir="auto">Expected behavior</h1>
<p dir="auto">Launching programs inside the terminal should not impact how/when newlines are preserved.</p>
<h1 dir="auto">Actual behavior</h1>
<p dir="auto">Newlines are preserved when copying multi-line output. After certain (fullscreen?) applications are launched they no longer are preserved and pasted output ends up on a single line.</p>
<h1 dir="auto">Isolation notes</h1>
<p dir="auto">Vim isn't the only program this happens with. At first I noticed copy inside tmux wasn't working the way I expected but then I noticed it happens just by launching and closing programs like vim and htop. I did a quick scan over the other copy paste newline bugs and none of them described this behavior but I might have missed one; sorry if this is a duplicate but I don't think it is.</p>
<p dir="auto">Your Windows build number: 10.0.18890.1000</p>
<p dir="auto">What you're doing and what's happening: Acrylic transparency is turned on in config and working when window is active. But as soon as the window becomes inactive the acrylic transparency turns off. Turns back on when window becomes active.</p>
<p dir="auto">What's wrong / what should be happening instead: Acrylic transparency should likely remain on. Especially in multiple monitor instances, where the window may remain at the front of the stack used for monitoring. Transparency is typically used to show when something is inactive or disabled. So transparency on when active and transparency off when inactive is the opposite of what is expected.</p>
