With swap interval 0, i.e. sync-to-vblank disabled. This can be necessary for unthrottled drawing with Xwayland: 1) One buffer can be scanned out 2) One buffer can be pending in the kernel for a page flip 3) One buffer can be pending in the Wayland compositor Therefore, with 3 buffers, the frame-rate could be capped much lower than the throughput the GPU is capable of, in the worst case at the Wayland compositor refresh rate. (The native Wayland EGL backend always uses up to 4 buffers) Leave the maximum number of buffers at 3 for swap interval != 0, it's sufficient in that case to always be able to queue one frame ahead of time. https://gitlab.gnome.org/GNOME/mutter/-/issues/1455 https://gitlab.gnome.org/GNOME/mutter/-/issues/1462 Cc: mesa-stable Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Adam Jackson <ajax@redhat.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/7033> |

`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://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 `Freenode's #dri-devel <irc://chat.freenode.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://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
