strace of qtconfig3

Comment 2 Ngo Than 2003-11-07 10:26:39 UTC
Hm, it looks like that useXft is disable in your config file.
Please start "kcmshell fonts" and check if "Use anti-aliasing for
fonts" is on

Could you please send your $HOME/.qt/qtrc.

Comment 3 Gérard Milmeister 2003-11-07 11:35:52 UTC
Created attachment 95790 [details]

Seems alright. Notice, that delete .qt and .kde to restart
cleanly. I also checked the settings in kcontrol and qtconfig3.

Comment 4 Gérard Milmeister 2003-11-07 12:02:14 UTC
Strange, strange. I started qtconfig3 remotely via ssh from an
RH9 box. Now fonts are antialiased, although a bit small.
Maybe related to this:
On both machines with the same NVIDIA driver 4496,
on running glxgears, on FC1 I get a
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
on RH9, I don't.
The NVIDIA driver doesn't need dri, and on both machines
Load "dri" is commented out. So far all OpenGL apps work
as expected on FC1, so this warning seems to be harmless.
Perhaps I will open a separate bug for this.

Comment 5 Gérard Milmeister 2003-11-07 18:14:11 UTC
It looks like the same problem as in bug #108672 is at work.
I switched to TwinView instead of Xinerama, and the fonts
in Qt and KDE display anti-aliased.
Unfortunately TwinView has its own issues.

Comment 6 Vitaliy Fuks 2003-11-07 19:15:25 UTC
Just to confirm the problem

Same machine, Red Hat 9 and FC1, using same XF86Config.

RH9 with Xinerama has true type fonts everywhere.
FC1 with Xinerama enabled does not have truetype fonts in KDE/qt apps.  

Disabling xinerama restores truetype-ness.

Comment 7 Jacek Piskozub 2003-11-07 20:23:26 UTC
Same problem with dual monitors. No anti-aliasing with xinerama, nice
fonts with TwinView.

Comment 8 Scott Phipps 2003-11-11 17:19:55 UTC
I have also run into this problem using a radeon 7500 and xinerama. 
The on bit of info I have to add is that I upgraded the qt in redhat 9
to 3.1.2-14 quite some time before Fedora Core came out and the fonts
were fine in qt apps with xinerama enabled.  I also play with a DTP
app called scribus that is qt based, and it will sometimes hang on
start related to fonts.  It does not ever hang when xinerama is disabled.

Comment 9 Ngo Than 2003-11-13 13:53:17 UTC
could you please try to install XFree86-4.3.0-2 from RHL9 in Fedora
Core. Does this problem still appear?

Comment 10 Scott Phipps 2003-11-13 17:51:33 UTC
I installed but of X from RHL9 and this was the outcome.  I first
downgraded only the Xfree86 rpm with no change in behavior.  I then
downgraded XFree86-libs XFree86-libs-data and XFree86-xfs.  I then
restarted X and the problem was gone.  Qt apps looked great and all
was well.  I then upgraded back to the stock Fedora rpms for XFree86,
-libs, and -libs-data, and the problem returned.  I then upgraded
XFree86-xfs to the stock Fedora so I would be back in sink with a
stock Fedora install.

Comment 11 Vitaliy Fuks 2003-11-13 21:38:59 UTC
I can confirm that downgrading to XFree86-libs-4.3.0-2 from RedHat 9
fixes the problem.

I installed the RPM while being logged into my (ugly-looking) KDE
session, then ctrl-alt-backspace and logged in again.  Problem is gone.

Comment 13 Mark Vevers 2003-11-20 15:40:41 UTC
Please see bug 110497 and note:

I've tried the new XFree86-libs but with the old libXrender library
and that fixes the problem.
If I put libXrender.so.1.2 back in all works OK
If I put libXrender.so.1.2.2 in it breaks ....

Comment 14 Mark Vevers 2003-11-20 16:00:21 UTC
Just looked at source RPMs for new RH90 Xlib packages and note that Xrender/render 
was upgraded to 0.8.3 - I suspect a prime candidate for the introducing/exposing the 
I don't know the insides of X well enough to work out the problem on my own but am 
more than happy to provide any debug logs required.  

Comment 15 Mark Vevers 2003-11-20 16:27:30 UTC
This may be related - found this on Mandrake ..... 

Comment 16 Mark Vevers 2003-11-20 17:18:04 UTC
Confirmed - Xrender.c 1.18 fixes the problem. 
From: http://x2.freedesktop.org/cgi-bin/cvsweb/xlibs/Xrender/Xrender.c 
  Make Xrender depth checks work with broken Xinerama code 

Comment 17 Charlie 2003-11-25 00:17:24 UTC
I believe this bug is now present in Redhat 9 after the recent update
of X packages published through RHN (RHSA-2003:288).

Comment 18 Ngo Than 2003-11-26 17:12:22 UTC
ok it seems a problem in XFree86

Comment 20 Mike A. Harris 2004-02-17 18:39:47 UTC
libXrender 0.8.4 has been released, which appears to contain a
fix for this problem.  I'm upgrading to it currently for Fedora
Core development.

Fixed in XFree86-4.3.0-58

Comment 21 Richard Cunningham 2004-02-19 11:09:32 UTC
As bug 110487 is marked as a duplicate of this bug for RH9.
I notice that a new version of XFree86 has come out for RH9
(XFree86-4.3.0-2.90.55) for which this bug is still not fixed. Is the
suggested fix for RH9 to get the lastest fedora development package?

Comment 23 Mike A. Harris 2004-02-19 12:19:34 UTC
As an additional note for Red Hat Enterprise Linux customers who may
experience this problem as well, as noted above for Red Hat Linux 9,
the current fix for this is considered experimental only for now and
not yet tested and production stable.

Since we release quarterly updates for RHEL 3, if the new Xft library
is considered to be stable in time for the next RHEL 3 quarterly
update, this fix may get included.  Otherwise it will likely wait
until the next quarterly update.

The important thing is that the fixes are widely tested before
being included in any official OS updates for RHEL 3 and/or RHL9
and/or Fedora Core 1.

Hope that helps clarify things a bit.
