Three things "seem to me..."
It seems to me that this issue has been going on since Monterey?
It seems to me that there is currently no fix.
Finally it seems to me there are bigger problems of which to take issue.
First of all, don't sit in your chair staring at the login screen getting mad. Login, and then move along.
Here is my biggest issue: I updated to Ventura 13.3.1 and soon discovered I had no 'write' access to an NTFS partition through Paragon NTFS for Mac that came with an external disk drive. 13.3.1 broke it. I use it for BOOTCAMP but its nice to write to it on macOS instead of it mounting as read-only. While trying to resolve that I broke other things leading to a Time Machine reinstall and multiple recovery mode Ventura reinstalls. Other software was equally broken. Only after resolving that "Ventura update" problem did I decide to look into changing the ugly login screen. Oh well, my blood pressure has returned to normal and the ugly login screen isn't going to get to me. Just as in MS Windows, Apple will provide sufficient "If it ain't broke, fix it with the biggest hammer to be found" issues to well and truly **** me off.
