This allows clients to send high color precision wl_buffers to servers which support the format. Use the EGL_EXT_config_select_group extension to put these 16 bpc unorm formats into a lower priority config select group 1, so they don't get preferably chosen by default by eglChooseConfig(), but must be explicitely requested by client applications which really need the high color precision of these 64 bpp formats and are happy to pay the potential performance impact. Successfully tested with KDE Kwin 6.4, and the GNOME Mutter 50 development branch, which has been enhanced to support these formats, also for direct scanout, and with Weston 13, which is also able to directly scan out to a 16 bpc framebuffer on suitable AMD gpu's.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. 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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_).
