Derek Foreman 3c0c2465f3 egl/wayland: Properly clear stale buffers on resize
The following chain of events results in an incorrectly sized buffer
persisting beyond its useful lifetime, and causing visual artifacts.

buffer is attached at size A
window is resized to size B
rendering takes place for size B
window is resized back to size A
swapbuffers with damage is called

In this scenario, update_buffers fails to recognize that the surface it's
about to commit is a different size than it has rendered. The
attached_width and attached_height are set incorrectly, and periodic
flickering is observed.

Instead, we set a boolean flag at time of resize and use this at the time
we latch the window dimensions as surface dimensions to decide whether to
discard stale buffers.

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

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install

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
