           Summary: Text is unreadable/completely mangled.
           Product: Mesa
           Version: 7.10
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: freedesktop.org at datademons.com

Example of mangled text.

My card is an old Radeon 9200 (rv280).

Using debian stable, w/mesa 7.7.1, text in opengl applications renders
properly, but mesa is very slow, so I decided to try out mesa 7.10 from debian
testing.

With debian testing (mesa 7.10), and unstable (mesa 7.10.2), the text is
completely mangled and unreadable.

I will attach a screenshot of an xbmc screen from my htpc that shows the
mangled text.  Other OpenGL apps behave the same way; all the text is
completely unreadable, but everything else renders beautifully (and quickly!)

Running OpenGL applications with LIBGL_DEBUG=verbose yields no errors other
than:

libGL: Can't open configuration file /etc/drirc: No such file or directory.
libGL: Can't open configuration file /home/htpc/.drirc: No such file or
directory.

The relevant entries from my dpkg listing:

ii  libgl1-mesa-dev                     7.10.2-1                     A free

ii  libgl1-mesa-dri                     7.10.2-1                     A free

ii  libglu1-mesa-dev                    7.10.2-1                     The OpenGL
utility library -- development files
ii  mesa-common-dev                     7.10.2-1                     Developer
documentation for Mesa
ii  mesa-utils                          8.0.1-2                     
Miscellaneous Mesa GL utilities

Adding the option: Option NoAccel true to xorg.conf makes the text render
properly in all versions of Mesa, but as you'd imagine, makes programs unusably
slow.

Let me know if you require any other information from me.
