According to wine tests, some apps can allocate very small ATI1/ATI2 textures levels. The issue is that the CPU versions of these textures are stored in buffers which size is the same as if the format was uncompressed. Thus the content filled cannot possibly be correct for these levels. The tests seems to hint when rendering with these levels the output is bad, but at least it the runtime shouldn't crash when using them. Previously nine would read outside bounds (found with asan) in this scenario, as the gallium helper copies a full compressed block. Instead do not copy anything for these levels.

`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/>`_.
