Hi,I had a touchpad issue with my XPS 15 9510，The touchpad is intermittently laggy and inaccurate. The problem does occur on Windows and Linux both. While in the bad state, the cursor moves more slowly and it's much more difficult to make precise movements.

I captured a Xorg log (event11 - DLL0945:00 04F3:311C Touchpad: kernel bug: Touch jump detected and discarded) When Touchpad cursor lag happen in Linux. The same problem happens while running Windows 10 or Windows 11.

I've tried disable i2c_hid pm in windows and still problems.

Is it a hardware problem or a software problem ?
