<h1 dir="auto">Steps to reproduce</h1>
<p dir="auto">Resize the Terminal from the bottom or double click to make it full screen. Any vertical resizing will do it.</p>

<h1 dir="auto">Expected behavior</h1>
<p dir="auto">Everything draws properly and the background color fills the window.</p>

<h1 dir="auto">Actual behavior</h1>
<p dir="auto">The background doesn't fill and black rectangles fill it instead. Improper redrawing.</p>
