Subject: Input Lag and Touchpad Issues with Unity (New Input System) — ZenBook Duo 2025 UX8406CA
Body:
Hi ASUS Team,
I’m experiencing a persistent input issue with my ZenBook Duo 2025 (UX8406CA) specifically when using Unity Editor with the New Input System enabled.
🟡 Issue Summary:
When Unity Editor is open (no compiling or runtime), the touchpad input lags, sometimes freezes for several seconds.
Right-click stops working entirely.
Occasionally, the touchscreen and keyboard become unresponsive or behave erratically.
This only occurs in Unity — other heavy apps like Rider, Chrome, and Visual Studio do not trigger the problem.
Happens only when the keyboard is docked. Wireless use is stable.
:white_heavy_check_mark: Troubleshooting I've Done:
Installed latest ASUS BLE Precision Touchpad Driver (v26.0.0.4)
Reinstalled ASUS System Control Interface v3 and ScreenXpert
Disabled Fast Startup and all power-saving options (HID, Bluetooth, I2C)
Performed a full EC reset
Tested with external mouse and keyboard – same issue.
This looks like a firmware or driver-level conflict with Unity's New Input System and the docked touchpad/keyboard mode.
:open_mailbox_with_lowered_flag: I also submitted a support case (E25040010542-0002 → N2504007359-0002), but it's been over two weeks without a reply. I'm hoping to get more visibility here.
Please let me know if there are any driver updates in progress or workarounds I could try. Thanks in advance!
