Hello everyone,
I've received my shiny new P52 about 2 weeks ago. So far, things have been excellent. However, starting last week I noticed the touchpad behaving weirdly seemingly at random. After a random amount of time - which can range from approx. 30 minutes to multiple hours - a huge latency spike kicks in when using the touchpad. The touchpad and mouse buttons still work, but moving the mouse pointer feels extremely sluggish as the delay is within a 3-digit millisecond range.
Neither the keyboard, nor the trackpad are affected by these latency spikes. So far, these spikes went away after a short amount of time, ranging from a couple of seconds to about 2 to 3 minutes. On some (seemingly random) occasions however, inputs from either the touchpad or the mouse buttons at the bottom cause a BSoD on my fresh (and updated) Windows 10 install.
Here's a picture of the BSoD generated from the Windows minidump using BlueScreenView:

I've also thrown the minidump into the Windows debugger, which apparently points to the ETD.sys driver (which is the driver for the ELAN touchpad) being the cause for the system crash:

Unfortunately, I have zero experience in debugging the Windows kernel and Windows drivers, hence this is the only thing that I'm able to come up with right now.
I'm also running an Arch Linux installation (Linux 4.19) on a separate drive where I was not able to encounter this issue (neither latency spikes or kernel panics related to the touchpad) yet.
Does anyone have an idea what's going on here? I've already tried rolling back drivers to the ones supplied through Windows Update. These appear to be the same version as the drivers that Lenovo ships on the support page for the P52, though.
Thanks in advance!
EDIT (11/7/18): There are also other threads describing the same issue here on the Lenovo forums, see:

I am running Windows 10 1809 (including all Windows and driver updates). My P52's BIOS is updated to version 1.14 which is the latest version at the time of writing this post.
