Description gora 2003-10-21 08:02:40 UTC 
Tilde, vector, Line Above are not shown correctly.  Symbols with this signs have
italic font properties so the top of the char is slightly moved to the right
while tilde sign for example stays on the same place. This bug is not obvious
for small letters but  for capital type letters it is perfectly seen. I'll try
to atttach the example of the formulae showing this bug.

Can confirm this with OOo 1.1.0(en) on Win98, with attached bugdoc and
"from scratch".
Comment 3 thomas.lange 2003-11-10 08:17:24 UTC 
It looks perfectly well with OOo 1.1 and Win XP.

TL->HDU: Please have a look. I remember Win98 having special problems

Can you also attach a screenshot?

Comment 8 hdu@apache.org 2003-11-11 10:03:53 UTC 
HDU->BH: Currently Math places arrows, tildes etc. over the middle of
the bounding box of the letter. The problem with this is that the
visual expectation of what looks good does not match math currently done.

I agree that for slanted letters the arrows, tildes, bars etc. should
be drawn adjusted to the slant of the base letter. If you agree please
set a target and reassign to TL.

original summary: "Displaying tilde, vector etc" Keywords, reassigning according
to new RFE-process.

Any changes?

Still does not work properly, with OO 2.3.1.  In writer, open an equation window
and type:

hat Y = %alpha + %beta{bar X} + %epsilon

Zoom to 200% if you can't see it clearly on the screen.  The bar over the X will
be displaced to the left relative to the letter.  I took a screenshot but can't
figure out how to upload it here.

Doesn't work on OOo 3.0.0 on OSX. bar X looks horrible.
