Description Forgotten User sxozS5NPY1 2005-10-08 11:45:03 UTC 
Hello,

I have the same problem as described in
http://bugs.gnome.org/show_bug.cgi?id=313646, but also with normal menus. A
screenshot is shown in http://www.bwalle.de/temp/fonts.png.

If anti aliasing is enabled, everything is ok. My ~/.fonts.conf is attached.

Comment 2 Forgotten User sxozS5NPY1 2005-10-08 13:20:02 UTC 
Seems to be a bug in nVidia driver if RenderAccel is enabled. Disabling this or
using the "nv" driver solved the problem.
Comment 3 JP Rosevear 2005-10-09 15:38:48 UTC 
CC'ing some people who might have insight into the nvidia driver.
Comment 4 Stefan Dirsch 2005-10-09 15:45:42 UTC 
We don't enable RenderAccel by default. Ccing Andy ... 
 
From the NVIDIA README: 
[...] 
        Option "RenderAccel" "boolean" 
                Enable or disable hardware acceleration of the RENDER 
                extension.  THIS OPTION IS EXPERIMENTAL.  ENABLE IT AT YOUR 
                OWN RISK.  There is no correctness test suite for the 
                RENDER extension so NVIDIA can not verify that RENDER 
                acceleration works correctly.   Default: hardware  
                acceleration of the RENDER extension is disabled.
Comment 5 Forgotten User sxozS5NPY1 2005-10-09 15:50:34 UTC 
Yes, I know. If I had found the reasone before, I hadn't reported the bug. 

It was my own fault, sorry for the inconvenience.
Comment 6 andy ritger 2005-10-09 21:19:58 UTC 
We're working hard at NVIDIA to stabilize "RenderAccel", at which point we'll
enable it by default in a future driver.  In the meantime, though, I'd still
consider RenderAccel experimental.

Thanks.

This has been fixed in release 1.0-8756. :-)

Option "RenderAccel" "boolean"

    Enable or disable hardware acceleration of the RENDER extension. Default:
    hardware acceleration of the RENDER extension is enabled.
