I was watching an LP of Minagoroshi and noticed the text backgrounds disappear a bit fast to read them comfortably.
Especially slow readers might have issues with the longer of the texts.
The text also doesn't show up in the backlog so you can't go back to them if you miss anything and they have some important stuff in them.
I'd propose lengthening the duration for which they appear.

They start showing up in the script at the part I've linked.
