Windows Terminal version

1.23.12681.0

Windows build number

Microsoft Windows NT 10.0.26100.0

Other Software

PowerShell 7.5.3
Windows 11 Pro Version 24H2 (0S Build 26.100.6725)

Steps to reproduce

  1. Open Windows Terminal on PowerShell 7
  2. Alt+Shift++ twice
  3. In each PowerShell panel, run a command via nodemon

Expected Behavior

Should adjust work

Actual Behavior

It suddenly crashes
The context is that I have a TypeScript-based Vite project and I keep running in the background:

  1. vite

  2. nodemon --watch src --ext ts --exec "tsc -p tsconfig.json --noEmit && tsc -p tsconfig.scripts.json --noEmit"

  3. nodemon --watch src --ext ts --exec "eslint ."

so that I can monitor the agentic AI while it's working on the project files
But apparently, it's too much for Windows Terminal to handle, so the window crashes

Curious. Does this still reproduce on 1.23.12811.0? We fixed a couple more windowing-related crashes in that version.

After Windows Terminal was updated through the Microsoft Store to version 1.23.12811.0, the issue seems to have been fixed

Though now I should create a feature request issue for resizing the splitted tabs 😅
