The downstream patches with the transparency settings were removed by Commit - rpms/gnome-terminal - 4df915ea6e3906291a352c98ed5855005f7dd1de - src.fedoraproject.org
ptyxis is the newer terminal, if you updated via gnome-software there is a bug where it doesn’t get installed.
It doesn’t not have GUI settings for transparency yet, there’s a post here explaining how to set it with the command line. Use dconf to set transparency for Ptyxis
I have also noticed when I close my lid, and reopen it, my computer freezes for a long time. It did not do this before.
After this occurs you may want to take a look at journalctl --no-host --no-pager --since=-10m
