Environment

Windows Terminal
Version: 1.0.1401.0

Platform ServicePack Version VersionString
Win32NT 10.0.19041.0 Microsoft Windows NT 10.0.19041.0

Steps to reproduce

  • Insert this into Terminal global application settings (I use a wide screen monitor 3440x1440):
"initialCols": 220,
"initialRows": 45,

Expected behavior

If you reach the bottom of the screen, any input should continue on the line you started
2020-05-21 (1)

Actual behavior

If I write more than 2 characters the cursor jumps up a few lines and continues there
2020-05-21

This behavior seems to be only happening with the default window and is completely sporadic. If I start a new PowerShell window it works fine, as you can see in the screenshots.

Additional info:
I use some PowerShell script code to tell me the size of the current window.

$host.UI.RawUI.WindowSize

Initial window:

Width Height
215 42

Second window:

Width Height
220 45

Maybe this is related somehow?
I made sure to disable all custom PowerShell scripts and configurations before I tested and wrote the issue.

btw: Windows Terminal is fantastic ❤️
