Title:
Phantom mouse wheel events without user input

Status in libinput package in Ubuntu:
Incomplete
Status in linux package in Ubuntu:
Incomplete
Status in mutter package in Ubuntu:
Incomplete

Bug description:
This doesn't occur with Firefox. But it occurs with Chrome AND gnome-
terminal.

What happens is that if I have more than one tab in focus, it moves to
the last tabs by itself.


Here is a screen capture of what happens.

I am running ubuntu 18.04.5 LTS, i have never had this issue before.
Issue started happening since yesterday.

This morning I applied my updates hoping that this will fix it, but
even then nothing happened.

I have known this to happen in another older laptop running an older
version of ubuntu as well.

journalctl -f gives me ths following:

```
Nov 23 15:28:36 xxxmymachinenamexxx gnome-shell[4051]: pushModal: invocation of begin_modal failed

```

Note that this error entry from the journalctl does not always appear
when the tabs cycle through like in the video, might be unrelated.



My graphics card is:

lspci |grep VGA

```
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

```


I thought initially it might be some key that is being pressed, so i ran screenkey when this happens, there was no key appearing, so it does not seem that this is a key being pressed.


I tail -f /var/log/syslog and /var/log/Xorg.0.log when i click on the tabs and it does this weirdness, nothing happens. So i don't have much information to give on this issue. Please get in touch with me if you want any information. I cannot push all my logs since it is a professional laptop.
