Windows Terminal version (or Windows build number)

1.11.2421.0

Other Software

  • top, htop, tmux
  • this bug was first reported by @georgewheatcroft issue #11183

Steps to reproduce

  • launch top and exit

Expected Behavior

  • blinking cursor

Actual Behavior

  • cursor not blinking anymore
  • to recover "tput cvvis" command was used. This sets the cursor again to very visible (a.k.a blinking)

If setting "TERM=linux" from "TERM=xterm-256color" as suggested in #11183 a lot of functionality is being lost. Here's a comparison of both terminal profiles, notice all the NULL entries for "TERM=linux":
