Gmail Display Density Changing On Its Own?

Hi,

I've noticed while logging in and out of Gmail, that the 'display density' has been changing on its own.

From "comfortable" to "compact".

Very annoying, as I think someone's been in my account toggling the settings.

However, no other devices are showing up as having logged in. Just my PC and my phone.

Has anyone had anything similar happen? How/why/what do you think caused it? How can it just change on its own? Besides a password hack, is there any other way someone could hack the Gmail servers and get into your account? For arguments sake.

I'm very concerned about my privacy.

Thanks :)
