I have a very similar machine here (170MHz SS5 with CG6) and I

because that was a machine that I _needed_ to get working, so I
stopped fussing and went back to 4.0 which I knew works perfectly.
I did notice a couple of things that may be useful though.
Firstly, just before the hang the last character output is slightly
misaligned. Not by a whole character cell - from memory the text
was a pixel or two higher than it was supposed to be. That suggests
to me that possibly address arithmetic is going slightly awry
somewhere.
Good eye! I think I'm seeing something similar.
I tried another experiment with a slightly more interesting text
pattern
than "XXXXX...". Using a repeating "123456789.", with four lines of
60
characters, the first line is fine, the second line is garbled, and
the
third and fourth lines are intact. There's a shell prompt after this,
but no more response to keyboard input.
The garble is interesting:
1234569.123456789.123456789.9.12345678*
Notice missing digits near the beginning. At "9.9.", the second "9."
and the remainder of the line look like they are displaced one pixel
down. The "*" represents a black cursor rectangle; there is another
cursor after the shell prompt.
