Unhappy font problems with gtk and nvidia driver

Hello,

with current version of gtk (2.8.12) and pango (1.10.3) I have problems with font rendering in every gtk-application. The fonts aren't rendered completely and text can't be read. The problem does only occur with the proprietary nvidia drivers!
Is there any patch available to fix this problem?

Regards,
Alexander

PS: debian sid with NVIDIA-Linux-x86-1.0-8178-pkg1 + some patches

Can you capture this problem in a screenshot?

Also, please generate and post an nvidia-bug-report.log.

Thanks,
Lonni

The screenshot shows the problem with the fonts. I can select the text with my mouse so that it will be repainted and can be read.

Hm, how can I generate a usable nvidia-bug-report and where should I post it?

Regards,
Alexander

Run as root:

nvidia-bug-report.sh

it will generate bug report and tell you what to do next.

Ah, thanks. I've generated a nvidia-bug-report.log and sent it to linux-bugs@nvidia.com.

This is a RENDER acceleration bug in Nvidia's driver. Turn off RENDER acceleration...

I have exactly the same problem
And there are many threads in forums.gentoo.org
It's a problem with GTK 2.8 and RenderAccel.
GTK 2.6 didn't have that problem.

If RenderAccel is active and fonts are not antialiased the problem occurs.
If RenderAccel is disabled and fonts are not antialiased the problem doesn't occur.
With font-antialising and RenderAccel enabled everything is fine, too.

regards Dennis

The next driver release should correct the majority of known RenderAccel bugs.

Thanks,

I had the same problem but when I updated cario from 1.0.4 to cairo-1.1.1_alpha20060216 the problem is gone.

This bug should be fixed with 1.0-8756.
