I just took the f(x) definition and replaced all 'x' with 'X' and put it straight into F1(X) defintion. Same problem! We can now eliminate CAS.

I've just tried scrolling, zooming etc. in Function's plot view after defining F1(X) as f(X) in Function's symb view with f defined in the CAS screen. After a minute or so I didn't experience any crashes or lock-ups. The plotting speed could certainly be improved.

Have you tried the above after starting with a clean slate? Perhaps there are some corrupted data structures in your calculator's memory. (While not giving you a completely clean slate, issuing the CAS "restart" command [WARNING: this will purge your CAS definitions] followed by shift+Esc and then a full reboot (shift + On [you might want to wait a tiny bit to ensure that the calculator state has been saved] and then On + Symb) will get you a good part of the way there.)
