Windows Terminal version

1.22.12111.0

Windows build number

10.0.26100.0

Other Software

Any games (e.g., Limbus Company, Delta Force).

Steps to reproduce

  1. Launch Windows Terminal.
  2. Launch a game.
  3. Attempt to interact with the terminal's UI (e.g., by typing).
  4. Observe that the terminal's GUI is frozen.

Expected Behavior

The Windows Terminal should remain responsive and usable, even when a resource-intensive game is running in the background.

Actual Behavior

The terminal's GUI becomes unresponsive. Keystrokes are buffered but not rendered, and the UI does not
update. After a long, indeterminate period, the terminal might process the buffered commands all at once
before freezing again.

We have captured crash dumps during these periods of unresponsiveness and identified the following consistent exception details:

  • Exception Code: 0x80000003 (A breakpoint was reached)
  • Faulting Modules & Call Stacks:
    * Scenario 1: Playing Delta Force
    * Faulting Module: Win32u.dll
    * Stack Trace: in32u!NtUserGetMessage
    * Scenario 2: Playing Limbus Company
    * Faulting Module: Win32u.dll
    * Stack Trace: coreclr!Thread::DoAppropriateAptstateWait
    Dump files are available upon request.
