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.

Seems to be a bug in nVidia driver if RenderAccel is enabled. Disabling this or
using the "nv" driver solved the problem.

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.

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.

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.

--> Enhancement

Comment 8 Stefan Dirsch 2006-04-18 10:29:34 UTC

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.
