Description Ian Pilcher 2006-03-24 16:28:52 UTC
Description of problem:

When GNOME is *not* running, many Gtk apps display somewhat ugly fonts.  I am
unable to determine if this is due to font rendering or font selection.  I
have observed this behavior in the following applications:

  - gdm
  - system-config-securitylevel (KDE and "failsafe" session)
  - GIMP (KDE)
  - Firefox (KDE)

I have *not* seen this behavior in Thunderbird.  Even more interesting, I do
not see this behavior in Firefox when it is started by Thunderbird (by
clicking on a URL in an e-mail).


Version-Release number of selected component (if applicable):

gtk2-2.8.15-1


How reproducible:

100%


Steps to Reproduce:

1.  Log in to KDE or a failsafe session.
2.  Start a Gtk apps, such as system-config-securitylevel
3.  Note less than attractive fonts.
4.  Log in to GNOME.
5.  Start the same app.
6.  Note more attractive fonts.
  

Actual results:

Font quality varies.


Expected results:

Font quality should not vary.


Additional info:

This is a regression from Fedora Core 4.

Screenshots coming.

Might this be related to bug #186323?  In both bugs Gtk apps are failing to
honor *either* the KDE or GNOME settings when GNOME is not running.

That's GNOME, not "GNONE".  Aaaaaaaaargh!

Setting the severity to "regression" is the normal way to report it. Don't use
the subject line for that. Thanks for the report.

I didn't even know that was there.  Thanks!

Comment 7 Ian Pilcher 2006-03-27 17:47:30 UTC
I'm not sure about the gdm and failsafe session cases, but I have determined
that the problem only appears under KDE when "sub-pixel hinting" is turned
on in the KDE Control Center.  Needless to say, turning it off is a less
than optimal workaround for LCD users.

Attempting to change the summary accordingly...

Probably related to bug #187688.


Comment 9 Roberto Ragusa 2006-04-06 22:21:38 UTC
Launching Firefox with "MOZ_DISABLE_PANGO=1 firefox" solves the problem for me.


Comment 10 Rex Dieter 2006-05-13 17:04:34 UTC
*** Bug 187688 has been marked as a duplicate of this bug. ***

Comment 11 Rex Dieter 2006-05-13 17:06:40 UTC
Maybe this should be assigned to pango (as was 187688), since this seems to
affect only pango-enabled gtk2 apps.

Comment 12 Matthias Clasen 2006-06-20 05:09:06 UTC
Reassigning pango bugs to Behdad.

Comment 13 Behdad Esfahbod 2006-06-20 20:40:06 UTC
I doubt this is Pango.  It looks like Gtk+ not loading font options if
gnome-settings-daemon is not running.  I don't know how that's supposed to work,
but if firefox spawned by thunderbird works, it may be a race condition
somewhere making gtk+ not seeing the settings as it tries to load them. 
Assigning to Gtk+.

As for being a regression, that's probably because of moving from Xft to cairo.

Fedora Core 5 is no longer maintained. Is this bug still present in Fedora 7 or
Fedora 8?

This bug is open for a Fedora version that is no longer maintained and
will not be fixed by Fedora. Therefore we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen thus bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
