Description Mark Hiles 2008-05-16 15:03:50 EDT
Description of problem:
Fonts are blurred and unreadable when using specific applications. 

I first encountered the problem when attempting to use applications through
Crossover Office 6.2. I assumed it was due to new components in Fedora 9 and was
going to wait until the next release of Crossover.

But after trying different font settings, I also found the problem in other

Steps to Reproduce:
1. Use 'Appearance Preferences' in Gnome and select the 'Fonts' tab.
2. Select 'Monochrome'.
3. Open OpenOffice.org Writer.

I've attached an image to this report.

Comment 2 Matěj Cepl 2008-05-16 17:07:24 EDT
To take some more ordinary application (OOo does some thing their own way) --
does it happen with gedit as well?
Comment 3 Mark Hiles 2008-05-17 02:45:41 EDT
The problem only appears to affect OpenOffice.org and applications running
through my installation of Crossover Office. 

Incidentally, the problem does not seem to occur in the version of wine in the
Fedora 9 repositories. 

Perhaps this is a bug that only now affects OpenOffice.org and has been solved
in recent versions of wine?
Comment 4 Caolan McNamara 2008-05-17 06:00:30 EDT
And what version of OOo is that exactly, rpm -q openoffice.org-core
sounds a bit like bug 443735

Please give the output of "locale", the font listed as "Application Font" under
gnome preferences and the output of "fc-match thatfont", e.g. "fc-match Sans",
and your video driver e.g. grep "drivers" /var/log/Xorg.0.log
Comment 5 Mark Hiles 2008-05-17 12:25:26 EDT
I had a look at bug 443735. That bug seems to refer to specific fonts and how
they are displayed in the font selector. It occurs when font smoothing/hinting
is turned on. My bug affects all fonts in the application when font
smoothing/hinting is turned off. It also says that the bug was corrected when
they installed a newer version of OOo. But the version that I'm running is even

My application font is Sans. Here is the output of the various commands you
asked for:

[mark@localhost ~]$ rpm -q openoffice.org-core

[mark@localhost ~]$ locale

[mark@localhost ~]$ fc-match Sans
DejaVuSans.ttf: "DejaVu Sans" "Book"

[mark@localhost ~]$ grep "drivers" /var/log/Xorg.0.log
(II) Loading /usr/lib/xorg/modules/drivers//nv_drv.so

Comment 7 Caolan McNamara 2008-05-18 15:22:27 EDT
I see this weird-ass thing with the "monochrome" setting for fonts on a F-9 box
with a nvidia and the "nv" driver at least. It goes away if I change the driver
to "vesa" fwiw
Comment 8 Sudheer Satyanarayana 2008-05-19 01:43:29 EDT
Thinking this problem was specific to OpenOffice.Org I filed this bug report
Comment 9 Caolan McNamara 2008-05-21 08:14:59 EDT
And it also goes away if Option "NoAccel" is used in /etc/X11/xorg.conf with nv,
and I *dont* see this problem on the laptop with a i915 driver

Do you mean that component xorg-x11-drv-nv is more appropriate for this bug?
Comment 11 Caolan McNamara 2008-05-21 09:53:31 EDT
Well, its the only driver where I can reproduce it. Definitely not xorg-fonts
Comment 12 Matěj Cepl 2008-05-29 09:43:36 EDT
OK, let's make ajax happy.

Attached is a simple cairo test-case that reproduces it for me

add behdad just in case the cairo guys are interested
Comment 16 Behdad Esfahbod 2008-06-03 11:58:21 EDT
Kind of a known driver bug IIRC.  mclasen should know better.
Comment 17 Matěj Cepl 2008-06-04 09:00:18 EDT
Looks like it may be reproducable nvidia driver as well -- bug 449867 looks similar.
Comment 18 Bug Zapper 2009-06-09 20:54:25 EDT
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
Comment 19 Adam Jackson 2009-07-09 11:01:21 EDT
Moving to rawhide to hide from the autocloser.
Comment 20 Adam Jackson 2009-07-14 17:56:28 EDT
Ben, give the testcase in comment #14 a shot when you get a chance.  ISTR fixing something similar in XAA back in the day, would be nice to know if it's gone for good now.
Comment 21 Matěj Cepl 2009-11-05 12:11:51 EST
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages (at least F12Beta, but even better if the very latest versions).

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

[This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
Comment 22 Bug Zapper 2009-11-16 03:06:10 EST
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Users who have experienced this problem are encouraged to upgrade to the latest update of their distribution, and if this issue turns out to still be reproducible in the latest update, please reopen this bug with additional information.
