<h1 dir="auto">Steps to reproduce</h1>

<p dir="auto">Open a session to one of the WSL containers. Open midnight commander and start scrolling with the arrows and tab between panes.</p>
<h1 dir="auto">Expected behavior</h1>
<p dir="auto">No additional characters appearing and disappearing. No changes to the borders.</p>
<h1 dir="auto">Actual behavior</h1>
<p dir="auto">Visual artifcats that don't seem to depend on the selected font. Both screensohts use different fonts - one is Inconsolata LGC, the other is Consolas. What seem to suffer the most are the borders.</p>
