Environment

Windows build number: Microsoft Windows [Version 10.0.18362.239]
Windows Terminal version (if applicable): 0.2.1831.0

Steps to reproduce

Open a session to one of the WSL containers. Open midnight commander and start scrolling with the arrows and tab between panes.

Expected behavior

No additional characters appearing and disappearing. No changes to the borders.

Actual behavior

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.

Yes, the artifact look the same and in the same place. I did not do any special settings though, if that matters.
