wrong display of slanted characters (on MS-Windows XP with official GNU Emacs v22.1)

[Peter Tury]

Hi,

I found that some slanted (italic) characters (especially `d') is
displayed in a wrong way sometimes: their upper right corner is
damaged _when I move the `point' from the position immediately after
them_.

I attach a picture about the problem: see the second d in the second line.

To reproduce the problem try this: run `runemacs -Q' > change to
fundamental mode > type  "d_x" > make the whole text slanted (M-o i) >
move point immediately after d (so cursor is on _): after a while (a
cursor blinking time?) d is damaged; the same happens if you move
point from the position immediately following d: either go up, down or
right. But if you move from other positions (e.g. from position
_before_ d, then d remains OK). This behavior seems to be independent
from cursor blinking.

Please fix this bug.

Thanks,
P
