<h1 dir="auto">Steps to reproduce</h1>
<ol dir="auto">
<li>Install Windows Terminal 0.5.2661.0 on a machine where tmux 2.8 has been installed and displaying correctly with previous Windows Terminal releases.</li>
<li>Open a WSL shell in a Terminal tab, inside <em>tmux</em>.</li>
<li>Run any command which displays text wide enough to use the rightmost column of the screen. For the example screenshots below, I used <em>env</em>.</li>
<li>After observing initial behavior, clear the screen with <em>clear</em> .</li>
</ol>
<h1 dir="auto">Expected behavior</h1>
<p dir="auto">Clean display of command output without character smear; all characters removed when screen cleared.</p>
<h1 dir="auto">Actual behavior</h1>
<p dir="auto">On initial run of the command in step 3, the rightmost character of the last line to contain one is "smeared" down the screen until another rightmost character replaces it, thus:</p>

<p dir="auto">When the screen is subsequently cleared, all characters displayed in this column remain visible:</p>

<p dir="auto">Thus far, I have only been able to reproduce this behavior inside a tmux session, although it was not observed until the latest Windows Terminal update. Additionally, I was using Cascadia Code as my terminal font also previous to that upgrade, without problems.</p>
