We were completely ignoring the primitive-restart case in the index-rewrite logic used to emulate triangle fans. Unfortunately, this case is way more complicated than a regular index rewrite: - we need to skip all primitive-restart entries when turning the triangle fan into a triangle list, which implies serializing the index buffer rewrite procedure (at least I didn't find any clever way to parallelize things) - the number of triangles can no longer be extrapolated from the number of indices in the original index buffer, thus forcing us to lower direct indexed draws into indirect draws and patching the indexCount value when the new index buffer is forged Reviewed-by: Jesse Natalie <jenatali@microsoft.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/16971>

Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
