Description

@vasily-codefresh

Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd]
Windows Terminal version (if applicable):

Any other software?

Microsoft Windows NT 10.0.18362.0
Windows Terminal (Preview)
Version: 0.9.433.0

Steps to reproduce

  • set display scaling to some custom setting. I use 130%
  • launch Windows Terminal

Expected behavior

fonts are scaled together with the rest of the system

Actual behavior

fonts are scaled weirdly with wrong size and visible artefacts

compare those screenshots.

  1. regular Windows console using Consolas 16pt. everything's fine here

  1. Windows Terminal using Consolas 16pt. somehow this 16pt is much larger

  1. Windows Terminal using Consolas 11 pt (almost matches size in Windows console). notice broken fonts

font rendering has visible artifacts on almost all letters, very notable on щ, й, з, б, р, ч and even English a and e. the screenshot is a lossless PNG, that's how Windows Terminal display those in real life.
