How to install Mesa 17.3.3 on Ubuntu 16.04 and 17.10

The latest MESA 3D graphics library 17.3.3 is now available in the Ubuntu-X team PPA repository for Ubuntu 16.04 and Ubuntu 17.10.

Mesa 17.3.3 implements the OpenGL 4.5 API, but the version reported by glGetString (GL_VERSION) or glGetIntegerv (GL_MAJOR_VERSION)/glGetIntegerv (GL_MINOR_VERSION) depends on the specific driver used. Some drivers do not support all the functions required in OpenGL 4.5. OpenGL 4.5 is available only when the context is created because it does not support compatibility context.

MESA 17.3.3 is a bug fix released one week ago. It fixes errors found since 17.3.2.

• Dota crashes when switching from game to desktop
• Calculation coloring Er: Incorrect alignment when the structure value is assigned to the structured SSBO
• Check whether the Python Mako template is installed.

For more details, see release notes.
