Environment

Windows build number....: 10.0.19041.0 (issue also seen on earlier versions)
Windows Terminal version: 1.4.3141.0
Pwsh version............: 7.1.0        (issue also seen on earlier versions)

Steps to reproduce

  • Open Windows Terminal
  • Maximize window to have more space for resizing (optional but makes it easier to reproduce)
  • Split the terminal horizontally and then vertically into panes
  • Resize bottom two panes up and down repeatedly using keyboard shortcuts

Expected behavior

The panes should resize without issues

Actual behavior

Windows Terminal crashes

Notes

  • The crash can happen at any given time while resizing panes. Some times you will be able to resize a lot, some times the crash happens instantly.
  • The issue have been observed on multiple different devices.
  • The issue is tested with pwsh, wsl and cmd running in the panes.
