Steps to reproduce

1. Join a call
2. Have the chat open
3. Move the window to a second screen to take notes in the other part
4. Colleagues post messages

Expected behaviour

Chat should stay scrolled to the bottom and always show the last messages

Actual behaviour

First message is like 80% visible and you can scroll to the bottom.
If you don't new messages are not shown

Talk app

Talk app version: 14+

So we don't scroll when the window is not focused, which is okay when the window is not visible, but if you do a recording it is rather annoying.

Maybe it would also make sense to use the page visibility api here... I regularly have a chat open on the second screen and it won't scroll because the window is not focused anymore 😕
Also in a call it totally makes sense 👍

I fear that is exactly what we are using:

spreed/src/App.vue

Line 249 in e454db1

document.addEventListener('visibilitychange', this.changeWindowVisibility)

The problem is this I guess:

spreed/src/components/MessagesList/MessagesList.vue

Line 817 in 2d3c1b2

if (this.isWindowVisible && document.hasFocus()) {

We still check for focus, not the visibility: https://developer.mozilla.org/en-US/docs/Web/API/Document/visibilityState
