Description amine 2009-04-25 18:27:56 UTC

Version:            (using KDE 4.2.0)
Installed from:    Ubuntu Packages

The bug happens randomly with or without Desktop effects.
I have changed the default set of fonts but the problem remained.

The attached snap shows the strange way fonts are being rendered.

Hi Amine,

I have been told that this may be a problem with sub-pixel hinting. Could you try to disable it to see if it fixes the problem? If this is the problem it may be fixed with Qt 4.5.1. Which version are you using? Thanks.

Comment 3 amine 2009-04-25 19:42:27 UTC

In system settings Anti-aliasing is set to System-Default. 
I have enabled Anti-aliasing and desactivated sub-pixel rendring.
Will stay in touch. 

I'm using QT 4.2

Comment 4 Dario Andres 2009-05-01 16:44:40 UTC

Could you double check your Qt4 version? (4.2 is not possible)
To find out it, just run "dolphin --version" in Konsole
Thanks

Comment 5 amine 2009-05-02 00:46:49 UTC

You are right it's in fact Qt 4.4.3.

The problem is still present even after disabling sub-pixel hinting.

Comment 6 Dario Andres 2009-05-02 00:48:26 UTC

Mh, may be it is related to your graphics drivers/card ... Which are they? 
But I still wonder if Qt4.5.1 could fix this
Thanks

Working with a nVidia G72M [GeForce Go 7400] graphic card with nvidia proprietary driver.

Comment 8 Dario Andres 2009-05-12 20:36:42 UTC

Please try to update to Qt4.5 as soon as possible and reopen this bug report to include the new situation. Thanks!

Comment 9 amine 2009-05-12 22:22:44 UTC

I'm under Qt 4.5 for 3 days now. 
Haven't noticed the font issue...yet.

Comment 10 Dario Andres 2009-05-12 22:27:38 UTC

Test it during 5 or 10 days so then will confirm this is fixed when using Qt4.5. Thanks!

Comment 11 amine 2009-05-18 01:34:57 UTC

The fonts are well rendered now after 10 days under Qt 4.5.
I think this bug can be closed now.
