Windows Terminal version

1.24.2372.0

Windows build number

10.0.19044.0

Other Software

broot 1.51.0 (Inside WSL)
micro 2.0.14(Inside WSL) (Optional here)
fish 4.0.2 (Inside WSL)
WSL version: 2.6.1.0
Kernel version: 6.6.87.2-1
WSLg version: 1.0.66
MSRDC version: 1.2.6353
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26100.1-240331-1435.ge-release
Windows version: 10.0.19044.6332

Steps to reproduce

  • Open Windows Terminal.
  • Ensure the profile is set to:
    “Profile termination behavior” = “never close automatically”.
  • Launch a shell (fish in WSL Debian).
  • Run a TUI program that uses the alternate screen and exits on Esc:
    For example run br (broot) and press Esc immediately(For Esc to work set up quit_on_last_cancel: true in broot config)
    or just try pressing CTRL + Q very quickly
  • Exit the program very quickly (near-instant Esc/q).
  • Observe the tab state and banner message.

Expected Behavior

No error.
“Profile termination behavior” should be “Automatic” I guess.

Actual Behavior

[process exited with code 259 (0x00000103)]
You can now close this terminal with Ctrl+D, or press Enter to restart.

Other issues with same error mention POPCNT

grep -o popcnt /proc/cpuinfo | head -1
output:
popcnt
