4.106.1. RHBA-2012:0288 — mesa bug fix update
Updated mesa packages that fix two bugs are now available for Red Hat Enterprise Linux 5.
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.
Bug Fixes
- BZ#442738
- 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 0x5bWith this update, the error message no longer occurs.
- BZ#508438
- 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.
All users of mesa are advised to upgrade to these updated packages, which fix these bugs.
