Original Pull Request: https://github.com/microsoft/terminal/pull/17257

State: closed
Merged: Yes

We need to lock the buffer when getting the viewport/cursor position.
This caused the UIA overlay to randomly fail to update.

Validation Steps Performed

  • Open a cmd tab and hold any key immediately
  • Repeat until you're somewhat confident it's gone ✅
