A new X1 Carbon 6th TrackPoint firmware version today "Fixed an issue where TrackPoint drift long time intermittently":
First off, the trackpoint firmware update for the X1 Yoga 3rd gen mentioned exactly this fix (see this post), so can we acknowledge that at least Synaptics seems to think that both systems share the same trackpoint problem? It would be nice if the Yoga thread could get more attention from mods/Lenovo.
And second, if this fix is the same as for the X1 Yoga, you might still see drift happening after installing it. The drift time has reduced for me (3-4 seconds rather than 8) on my X1Y3, but others in the Yoga thread report different results. Nobody says it fixes it to the point where performance matches older Thinkpads. There's still something not quite up to snuff about the hardware or the firmware even with this update.

I will let you guys know. I have the KH20. I first tried the Lenovo Vantage app - it doesn't show up there yet. So I just downloaded the fix directly. It instructed me to plug in the power adapter so it's some kind of low level hardware flash. This thing was driving me up the wall, but I guess I'll find out in an day or two if it worked ...

Problem for me, as I only use trackpoint and never a mouse or the touchpad. Make this laptop emensly frustrating to use.
As I try and reach for submit button after typing this, I'm fighting against drift.

After installing the firmware it is even worse. I am having a problem with drifting and clicking of the touchpad. It is not precise, it clicks randomly on its own and open/closes programs. For example i would click the x button to close a window and instead it will open the windows start menu, or it will act like if i am using three finger motion, or it will just move around.

I updated the firmware about 2 days ago. Unfortunately I have seen one case of the drift since then. It dissappeared after about 10-15 seconds of trying to put the cursor to the top left.
Happy to help however I can?

I'm getting this impression as well-- that it is a problem that cannot be fixed via software. This could be a problem inherent to the hardware design. The question is why does Lenovo continue to use the same trackpoint hardware for several generations of the Carbon (in this case) instead of correcting the design.
