Originally created by @JCKodel on GitHub (Jan 31, 2020).

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.592]
Windows Terminal version (if applicable): Windows Terminal (Preview) [Version 0.8.10261.0]

Any other software?

NodeJS, NPM and NativeScript.

Steps to reproduce

  1. Install NativeScript, following their quick setup (it requires node and npm): https://docs.nativescript.org/start/quick-setup (basically, npm install -g nativescript, just needing NodeJS and npm, does NOT need Android SDK or any of the other dependencies, AFAIK)

  2. Create some project with tns create

  3. In the result folder, type tns preview.

Expected behavior

The text should be rendered 100% equal on both consoles (not missing entire rows of text).

Actual behavior

Old Windows console:
image

(the NativeScript playground app requires the reading of this qr-code to preview the app on the phone).

New Windows Terminal:
image

(notice that the last row are missing from the QR-Code, so the preview app won't recognize the QR-Code).

The only difference between those screenshots are the terminal app (so it is NOT a NativeScript bug or something like that)

Thanks for the report! I think that, at the end of the day, this is a /dupe of #2089. The name probably doesn't seem correct, but it refers to how we determine the "right" side of the screen.
Since the QR code is made of colored space characters, and we think spaces are not meaningful sometimes, *boom*

I had the same problem and I discovered it was due to the fact that the font I was using was not a monospaced font(equally sized characters)
