I have a new XPS 15 9560 laptop with a precision touchpad (Microsoft drivers) running Windows 10 (1703, 64-bit). The touchpad generally works fine, but with two-finger scrolling sometimes I experience a 0.5 s lag OR the pad interprets the gesture as a pointer move (although I definitely use 2 fingers). The behavior is seemingly random, but it occurs quite often.
I disabled "pinch to zoom" in settings. I also tried increasing the touchpad sensitivity in settings and reducing the APPThreshold in the registry to 0 (Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\PrecisionTouchPad), but this didn't help.
Does anyone have an idea how to fix this?
Let me see what I can find, but do you happen to notice if the lag occurs on an external mouse? And if you go into Diagnostics (F12 at Dell/XPS initial boot screen) and run Diags, do you notice any of this odd lag there?
Thanks for your answer. The lag does not occur with an external mouse. It really appears to be related to the touchpad sensitivity or settings. The diagnostics did not turn up anything.
Thanks for the updates, can you Private Message me your Service Tag on the system? Please do not post it in the thread, let me know if you have any questions.
