Assuming you use continuation lines, and not truncation, does the
speed improve setting `cache-long-line-scans' to t? (Note that the
variable is automatically buffer-local, so be sure to set it in the
appropriate buffer, or use setq-default.)

Yes, I think so. You can see the backend used for a font by moving the
cursor over a character in that font and doing "C-u C-x =". The font
information will start with gdi: or uniscribe:

No, that is indeed very common.
