First, there is a problem if you do the following
vkCmdSetColorWriteEnableEXT(attachmentCount = 8)
vkCmdBindPipeline(GFX, with attachmentCount = 4)
vkCmdDraw()
vkCmdBindPipeline(GFX, with attachmentCount = 8)
vkCmdDraw()
Because in the dynamic state emission code we rely on the first
pipeline to figure the number of BLEND_STATE entries to prepare. This
is wrong, we should fill all entries so that the dynamic state works
regardless of the number of attachments in the pipeline. With regard
to the dynamic values, we should retain enable/disable values that do
not concern the current pipeline.
Second, 3DSTATE_WM was not always reemitted when the pipeline changed.
But since it is not emitted as part of the pipeline, this results in
inconsistent state being programmed.
Third, we end up disabling the fragment stage completely in some
cases. And that is programming the pipeline inconsistently and
triggering a hang on TGL.

`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 `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://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.
