Very interesting. The partial redraw problem seems to be gone when
cairo is disabled. I couldn't reproduce the bad case any more.
However I encountered another bug when cairo is disabled: did C-h h to
bring up HELLO, and Emacs crashed:
lisp.h:1543: Emacs fatal error: assertion failed: 0 <= size
Fatal error 6: Aborted
lisp.h:1543: Emacs fatal error: assertion failed: 0 <= size
Aborted
Thanks,
