I'm reporting a BT bug which affects multiple brands and models of laptops.
This affects BT mice and keyboards in the form of input lag and/or stuttering. Specifically, I see this issue on both a Logitech MX2S mouse, and a Microsoft Surface Arc one.
This issue does not occur on a 2019 HP Envy with an Intel 9260 WLAN M2 card. It also does not occur with a brand new Intel AX210 card I installed in the Envy. Unfortunately, the Spectre X360 has a soldered M2 card so it is not replaceable.
This lag issue appears to be related to BT LE (low energy) implementation on Windows 10 (2004 and later).
This occurs on the HP Spectre X360, Lenovo 13s G2, and Dell XPS 9310, and likely many other models.
Manufacturers need to be aware of Windows BT LE implementation and work to release a BIOS update that allows for proper BT device use. Asus, for example, seems to not have an issue with stutter/lag despite using the same Intel AX201 based WLAN/BT card.
Here is a link to the Dell XPS thread which has much discussion on workarounds, but no actual fix yet.
I hope HP is already working on this issue.

I'm having a similar issue using a Logitech MX Anywhere 2S mouse and Logitech MX Keys keyboard. Oddly, it only happens when I use them with my Envy x360, which I've had for about two weeks and not my Spectre x360, which I got back at the end of August.

Are you sure? Have you tried it? I've already tried a multitude of things (disabling power management in device manger, editing registry, updating Bluetooth drivers) and I'm hesitant to do something else until I know for sure it will work.
BTW, my current drivers are 220.127.116.11

Strange that the link got removed. A link to an Intel driver for a component in the laptop. With no explanation either.
Looks like the mods are not only unhelpful in providing a solution, but then become an obstacle to a solution as well.
Great customer service!
