Environment

Windows build number: [Version 10.0.19042.844]
Windows Terminal version: 1.6.10571.0

Any other software?
Ubuntu using WSL 1
Fish Shell

Steps to reproduce

Print any italic text to the terminal

Expected behavior

All characters should be italicized and fully visible.

Actual behavior

The last character before a newline is cut-off where the italic character would bleed into the next character. Note this occurs when using both Cascadia Code and FiraCode in my testing.

After further testing, we've determined that the issue is related to the cleartype antialiasing setting. Using grayscale eliminates the issue.
