Emacs Xft Jhd refresh

[Daniele Scarpazza]

Hi, I'm am reporting a graphical problem with emacs, the Xft-jhd branch.

The problem consists in incorrect character refresh. 
Described in very simplistic terms, when I type a character, the cursor 
advances but it leaves a trail after it.
If I type a backspace, the delete char remains on the screen, and if a type 
another character the two appear superimposed one over the other.
The same problem happens also with the messages which appear in the buffers and 
minibuffer.
All the messages appear one over the other. 

I have to type C-l all the time to force a redraws.

I have been unable to isolate the cause of the problem.
The problem does not appear under Slackware 10 or Fedora Core 4 distributions, 
but it appears in Red hat Linux Workstation:

Red Hat Enterprise Linux WS release 3 (Taroon Update 4)
Linux pc3643 2.4.21-27.ELsmp #1 SMP Wed Dec 1 21:59:02 EST 2004 i686 i686 i386 
GNU/Linux

I have recompiled freetype2 and the entire gtk+ without success.
Hope you would fix it.
Best regards,
Daniele
