After some use, Emacs display shows garbage characters instead of
normal text. Only those characters that are shown with the normal face
are replaced by garbage. Text shown as italics, bold, etc, remains
correct. I have no recipe to reproduce this. It usually happens while
reading news with Gnus, but I was unable to reproduce the problem by
duplicating the Gnus session (in particular, displaying again the
article that I was reading when the display got corrupted).

If you display the etc/HELLO file (with C-h H) and move the cursor
around the buffer, do you see garbage?

[I ask because I've seen glyph corruption in one particular computer
when doing that]

No. Just some blank boxes due to missing character sets. It takes 2
minutes to load and display the file on my Athlon 550 MHz, though.

Yes. Jason said that the time is spent looking up the fonts, which is
now much more thourough, but also much slower.

What default font you are using? (as reported by C-u C-x = before the
problem starts)
