Hmmm... I'm running a rawhide snapshot from the last couple of days
and I can't reproduce this. Wild guess: maybe it's locale-dependent?
What's the output of "echo $LANG" on your system?

Comment 3 Antti Andreimann 2004-10-18 08:39:27 UTC
I have latest rawhide snapshot.
System LANG=et_EE.UTF-8
For the test I ran oowriter from command line with:
LANG=en_US.UTF-8 oowriter
With my default locale OOo comes up in estonian, but the problem is
still the same.
What can I do? Is there any way to see exactly what fonts it is trying
to use?

Comment 5 Jon Burgess 2004-11-06 20:14:06 UTC
I see the same problem occuring with the latest packages.

The corrupted characters appear both in the menu system and the
documents themselves. I have added an attachment that shows my "about"

My default LANG = en_GB.UTF-8
I tried running it as "LANG=en_GB oowriter", "LANG=C" etc, but it
seemed to have no effect.

Comment 6 Ian Pilcher 2005-02-26 04:15:40 UTC
I believe that this may be video driver related.  I have had Fedora Core 3
installed on 4 different systems:

  - Homegrown dual-Pentium III with Matrox G200 (mga driver)
  - Homegrown VIA EPIA-M with built-in "CastelRock" graphics (via driver)
  - Homegrown Pentium III with Matrox G450 (mga driver)
  - IBM ThinkPad T30 with ATI Radeon Mobility 7500 (radeon driver)

Of these, I only see the font corruption on the ThinkPad.

I see this up through openoffice.org-1.1.3-6.5.0.fc3 on Fedora Core 3.
(The version of this bug should probably be updated.)

Comment 7 Ian Pilcher 2005-02-26 04:57:17 UTC
As I suspected, I can make the font corruption go away on the ThinkPad by

    Option  "Accel"     "false"

to /etc/X11/xorg.conf.

Not really a usable workaround, but perhaps this is really an X.org problem?

Comment 8 Dan Williams 2005-02-26 15:44:40 UTC
Kevin: can you help direct this issue where it needs to go?  It seems to be related to ATI X.org drivers 
specifically, no other graphics chipsets are affected.  OOo makes heavy use of XRender to draw the text 
which is probably where the issue is coming from.  In any case, we'll need some X people to help 

Comment 9 Kevin E. Martin 2005-02-27 18:15:25 UTC
Dan: There is a known issue with Render acceleration with certain Radeon cards.
 We will be disabling it by default in the next update.  In the meantime, you
can disable it by adding the following line to the "Device" section of your
xorg.conf file:

    Option "RenderAccel" "False"

This will only disable Render acceleration -- all other acceleration is still
enabled and should work fine.  When we work the remaining bugs out of the Radeon
Render accel code, we will reenable it by default.

Comment 10 Ian Pilcher 2005-02-28 07:01:18 UTC
Setting "RenderAccel" to "False" does appear to fix the font rendering issues
in OpenOffice.org.  So all that's needed is the bugzilla # of the Radeon
Render problem, and this can be closed as a DUP.

Comment 11 Dan Williams 2005-02-28 17:12:41 UTC
Ok, over to X.org then.

Adding bug alias "radeon-renderaccel" to make it easier to close
bug duplicates.

  to disable render acceleration by default in the "radeon" driver, as
it is
  currently broken (#136065,136941,149907,143401,143234)
