RHBA-2012:0288 - mesa bug fix update

Synopsis

mesa bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated mesa packages that fix two bugs are now available for Red Hat Enterprise Linux 5.

Description

Mesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides hardware-accelerated drivers for many popular graphics chips.

This update fixes the following bugs:

• Under certain circumstances, when using Mesa's DRI driver for graphics with accelerated 3D support, the driver could incorrectly produce the following error message:

  libGL warning: 3D driver claims to not support visual 0x5b

With this update, the error message no longer occurs. (BZ#442738)

• Mesa previously used a numerically unstable algorithm in an internal matrix inversion function, which caused the gluUnProject() and gluUnProject4() functions to return incorrect results. This update applies a patch based on upstream code that corrects the algorithm for matrix inversion used by Mesa. The gluUnProject() and gluUnProject4() functions now work as expected. (BZ#508438)

All users of mesa are advised to upgrade to these updated packages, which fix these bugs.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
