The change log didn't suggest the release would fix our issue, but I tried it anyhow hoping for a positive side effect... Unfortunately there was no change in behavior for me. In addition to libinput version rollback, touchpad firmware update, I've also tried disabling tablet mode, disabled power management for the touchpad and have scanned through every log I can think of with no errors present to clue me in. I am not sure at this point if we need a bios fix or if there is an issue in the touchpad driver itself. Regardless, I am just along for the ride at this point. Also of note was that while I was running Windows to install the firmware update, I didn't experience any touchpad issues, so I do not think this is a widespread hardware failure.
Dell released a new bios today... but no need to get excited as I've just flashed it and still seem to be experiencing the issue. Since flashing the touchpad firmware and bios updates, I've also moved up to kernel 5.15rc1 and libinput 1.19. Hopefully one day we will see the issue resolved.
Brand new XPS 15 9510 owner here and the touchpad has been sticky from the off. Remote dell support tried to fix the problem through a bios update but it hasn't made a difference so now waiting for Dell to send an engineer out. Pretty hacked off that an issue has happened so quickly, when it's such a known issue for Dell *but* happy with the support I received to date remotely. Let's hope they now deliver.
48 hours on from the promise of an engineer being sent out to fix the sticking touchpad, I've heard nothing. Have followed up with the engineer twice. Shame as Elgin seemed so helpful at first.
I recently made a new discovery on XPS 9510.I think this should be because Dell has not handled the boundary problem at the software level. or hardware design flaws. When the touchpad is in a accurate state, the left and right 8.2mm area is not available（https://www.dell.com/support/kbdoc/en-us/000184090/xps-9700-precision-5750-touchpad-functional-area#）. When the touchpad is laggy, the full touchpad area Available.
When the touchpad is in a precise state, you can move it up and down in the left and right 8.2mm area, and there is a chance that it will change to a laggy state
This problem should not be difficult to reproduce. Dell engineer, if this is a software bug and you don't know how to fix this problem, why not release a version of the firmware that is available in all area, so that there is no need to deal with boundary problems at the software level. Maybe this problem is solved?
I can confirm this exact same behavior on my XPS 9510, Windows 10. When the mouse pointer starts to become "sluggish", the very left and right 8.2mm edges of the trackpad function. When the mouse pointer acts normal, they do not function as per the most recent ELAN Touchpad Firmware update.
I tested that there is a difference on that behaviour, beetween using it in AC mode and battery mode. With AC, on 30 minutes usage, no laggy touchpad. When on battery, it slows down many times
I can confirm that the whole surface of the touchpad become usable when the lag happens. Otherwise, the very left and right 8.2 mm edges of the touchpad are unusable (Ubuntu 20.04).

The problem reappeared in windows, it seems that this problem has not been fixed yet.
Windows users can move up and down at 8.3cm on the left and right sides, and then move to the center, and the problem may appear again.

I hope Dell will find a solution to this problem.
I add that I have found this lag is present on elementary os.

Come on Dell, this is unacceptable, my old Inspiron 5567 works better with linux!

Many people are having the same issues with Latitudes. Video here, with many comments:
Anyone experiencing touchpad problems on his Inspiron 16 Plus 7610? (random taps and swipes, inaccurate finger tracking, etc...) : Dell (reddit.com)

I can confirm this exact same behavior on my XPS 9510, Windows 10. When the mouse pointer starts to become "sluggish", the very left and right 8.2mm edges of the trackpad function. When the mouse pointer acts normal, they do not function as per the most recent ELAN Touchpad Firmware update.
