This situation is happening, for instance, when the hardware is using the type FMT_8_8_8_8 (4 bytes) while the software was requesting a 3 bytes type. The width should be adjusted to the expected hardware size; otherwise, the last vertex is lost. Note: The rv770 didn't behave like this. This is definitely a hardware change between these gpus. This change was tested on palm and cayman. Here are the tests fixed: spec/!opengl 2.0/gl-2.0-vertexattribpointer-size-3: fail pass deqp-gles2/functional/draw/random/62: fail pass deqp-gles2/functional/vertex_arrays/single_attribute/strides/buffer_0_32_byte3_vec4_dynamic_draw_quads_1: fail pass deqp-gles2/functional/vertex_arrays/single_attribute/strides/buffer_0_32_short3_vec4_dynamic_draw_quads_1: fail pass deqp-gles2/functional/vertex_arrays/single_attribute/strides/buffer_0_32_short3_vec4_dynamic_draw_quads_256: fail pass deqp-gles3/functional/draw/random/117: fail pass deqp-gles3/functional/vertex_arrays/single_attribute/strides/byte/buffer_stride32_components3_quads1: fail pass deqp-gles3/functional/vertex_arrays/single_attribute/strides/short/buffer_stride32_components3_quads1: fail pass deqp-gles3/functional/vertex_arrays/single_attribute/strides/short/buffer_stride32_components3_quads256: fail pass Cc: mesa-stable Signed-off-by: Patrick Lerda <patrick9876@free.fr> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32184> |

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