Sequoia upgrade causes external mouse issues on external monitors?

Following the upgrade from Sonoma to Sequoia, my external mouse is drifting. This only happens with the cursor over the external monitors, which are connected through a docking station.

The computer: Macbook Air, with Apple M2 chip, 24 GB memory.

The mouse: Apple mouse, about 2021 vintage.

So far, I've tried:

Cleaning mouse optical area to ensure no debris is obscuring the sensor
Resetting pointers, including forgetting the mouse and reconnecting it
Rebooting machine
Changing pointer preferences for both trackpad and mouse
Reinstalling Sequoia

By "drifting" I mean that when the mouse is already moving, its movements are erratic, with a tendency towards the middle point of the two external monitors (it moves in different directions on different screens). The cursor does not move unless the mouse does, but a small up-and-down motion creates a significant side-to-side motion. There appears to be a slight bias for upward motion as well.

The only thing that changed causing this to happen was the upgrade from Sonoma to Sequoia.

Is anyone else having this issue? Thoughts on a solution? I'm tempted to do a clean install of Sonoma to roll back the upgrade, but that feels like going nuclear.

MacBook Air 15″, macOS 15.0

Edit:

As an update, I have tried with a trackpad and 3 other mice. The issue appears to be consistent across the bluetooth connection for pointers.

Wired mouse worked normally.
Wireless non-Apple mouse worked normally (USB connection)
Another Apple mouse had the same issue
Apple trackpad (external) has the same effect, but it's less pronounced than the mouse

Problem seems not related to external mouse or external screen, I also have it on 15.0.1 with the trackpad and without external screen. Magic mouse not connected via bluetooth.

It is re-occurring now within minutes, makes my laptop unusable!

(I even had difficulties completing this post, only succeeded after a full restart)

I do have the same issue with my Logitech M70 Triathlon since upgrading to Sequoia.

Dragging around a window fast on any screen causes the mouse to "loose grip" or it may not "lock" on the window at all. The M720 can use bluetooth or the logitech unified dongle. Tried both connection methods, same issue.

Then I connected my HP Travel mouse from work with my M2 MacBook Pro - issue gone.

It may be driver issue for some pointing devices in Sequoia but obviously not all.

Until the issue is resolved, the Logitech M720 is not usable with my Mac.

Same problem here. Intel MacBook from 2019. After Update to Sequoia (15.0.1) I often need to click 3 or 4 times on a button or link to cause the desired action. No problems with Sonoma.

Cherry Gentix BT Mouse via Bluetooth. No external monitor, only Time Machine driven connected through USB.

It gets really annoying.

I stand corrected. Two of my mice have a button that has reached "end of life" obviously. The M720 and now the same happened to my HP Travel mouse. Found an old Speed Link mouse and with the dongle plugged in to one of the monitors everything works fine. So the defective mouses tend to release the button for maybe milliseconds if they are not constantly pressed with hard force.

I'm having a similar issue with the Apple Mouse and AirPods Max Headphones.

Issue: mouse lagging in movement, frequent audio drops when playing music.

MacStudio M2 Max

MacOS 15.0.1

The issue started for me last week, shortly after the AirPod Max firmware upgrade on Oct. 22nd.

I have this issue too and I bought a new magic mouse thinking that the old magic mouse was to blame but the new magic mouse has a lag and it seems to be inconsistent. Sometimes it has issues and other times not. My new macBook Air M3 16GB running the latest update macOS Sequoia Ver 15.1. Magic mouse with USB C. I just don't get it.
