Fo sure, no sane person has a grass as their chat background or any background. That seems silly.
This is one of my "boomer" opinions.
I don't like transparency, backgrounds, or (most) animations anymore.
That said, I'm used to Liquid Glass now and I don't much care either way anymore. It's just not a big deal to me.
I've been using a grass wallpaper and lock screen on all my devices for something like 15 years now. It works great if you don't go out of your way to break it and then blame the user.
