It sounds like you have a peripheral that's generating unwanted mouse
wheel events. If the problem is still happening then please run 'xev' in
a Terminal window and move the mouse pointer over the little white
window. Now do you see new events being logged in the Terminal window?

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.
