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@lists.freedesktop.org ReportedBy: freedesktop.org@datademons.com
Created an attachment (id=45695) --> (https://bugs.freedesktop.org/attachment.cgi?id=45695) 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 implementation of the OpenGL API -- GLX development files ii libgl1-mesa-dri 7.10.2-1 A free implementation of the OpenGL API -- DRI modules ii libgl1-mesa-glx 7.10.2-1 A free implementation of the OpenGL API -- GLX runtime ii libglu1-mesa 7.10.2-1 The OpenGL utility library (GLU) 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.
