[Bug] Keeps freezing

Did you try to get some inertia on scroll by pulling rapidly to the left or the right?
When I zoom with center of axis remaining at the center it looks ok. As soon as I give it an impulsion, I see the drawing scrolling, then blank area (curve barely or no longer visible) and after 2 or 3 very slow refreshs it is frozen.
If you check the Num table, you'll see that there are a number of NaN or huge values. This could be another reason while the redraw fails.

(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.)

I just tried all what you said. I did more:
Using On + Apps + Esc as documented by Cyrille -> no improvement
Using the CFO menu, I "formatted C:" funny name, definitely a DOS legacy :-). This supposedly totally cleaned the memory.
I found the calculator a little faster after that but still crashing.
Anyway, as I mentioned in an earlier post, I replaced the f(X) call by the actual definition of the function so that CAS is no longer involved. Same result...

This is becoming mental, to me this is a bug, I didn't have the issue on the former version of the OS.
