"Text messaging iPhone 14: On iOS 17, the text message box becomes too large for me to read the message thread behind it when I’m responding to a text message. I can’t minimize the text box to see previous message(s). Anyone else having this issue?"

No. I have not come across this issue.
Report back if either of these fixes this...
A. Change Notifications Font Size:
Texts are notifications. So, see if changing the font size would work. Go here: Change the Font Size on your iPhone, iPad, and iPod touch - Apple Support
B. Perform a Restart:
Having just installed an update, perform a restart.
