[BUG] computer-use takeover minimizes all open windows on a dual-monitor Windows machine, every time, survives a full restart; reopened windows then auto-close within 2-3 seconds.

What's Wrong?
Environment
OS: Windows 11 Home 10.0.26200
Display setup: dual monitor ("HISENSE" + "HP 24ec")
Client: Claude Code
MCP server: computer-use (mcp__computer-use__*)
Description
Any computer-use screen-takeover action — including a single, bare computer_batch call containing only a screenshot action, with no clicks or typing — causes every currently open window on the desktop to minimize immediately, leaving only the desktop visible. Attempting to reopen a minimized window afterward causes it to auto-close on its own within 2-3 seconds.
Expected behavior
Taking a screenshot via computer-use should be non-disruptive — it should capture the current screen state without altering window state.
Actual behavior
All open windows minimize on every screenshot/takeover action, and any window reopened afterward self-closes within a few seconds.
What's been ruled out
-Reproduced independently three separate times in one session, ruling out:
-Remote-access conflict (TightVNC Server / Remote Desktop Connection / Quick Assist installed) — addressed, retried, still occurred.
-Stale local session — full OS restart, retried, still occurred.
-Stale MCP connection — server disconnected and reconnected mid-session, retried, still occurred identically.
Appears tied to the takeover mechanism itself on this multi-monitor setup, not fixable local/application state.
Impact
Unable to properly use computer takeover, limiting work capabilities.
What Should Happen?
Expected behavior
Computer-use should be non-disruptive — it should use the computer without altering window states.

Steps to Reproduce
Steps to reproduce
Have one or more normal application windows open on a dual-monitor Windows 11 machine.
In Claude Code, call mcp__computer-use__request_access for any app, then call mcp__computer-use__computer_batch with a single {"action": "screenshot"} step.
Observe: all open windows minimize to the desktop at the moment the screenshot is taken.
Try to reopen one of the minimized windows.
Observe: the reopened window closes itself within 2-3 seconds.

Additional Information
Additional notes
request_access returned "screenshotFiltering":"mask", tier "full", each time.
No clicks/typing/explicit close actions were issued in any reproduction — only request_access + a bare screenshot (and in earlier attempts, switch_display).
