<pre>TexSubImage3D is buggy when updating texture data from pixel buffer on Linux +
Mesa + Skylake. Size of the texture changes after updating data with
TexSubImage3D from pixel buffer.
Steps to reproduce:
1. download chrome from <a href="https://www.google.com/chrome/browser/desktop/">https://www.google.com/chrome/browser/desktop/</a> or use
latest chrome in your linux distribution
2. un chrome --enable-unsafe-es3-apis --ignore-gpu-blacklist
3. open url:
<a href="https://www.khronos.org/registry/webgl/sdk/tests/conformance2/textures/misc/tex-subimage3d-pixel-buffer-bug.html?webglVersion=2">https://www.khronos.org/registry/webgl/sdk/tests/conformance2/textures/misc/tex-subimage3d-pixel-buffer-bug.html?webglVersion=2</a>
4. All tests should pass.
5. You will see failure in the page.
This happens on Linux with Mesa 11.0 and 13.0, not on other GPU vendor or
Windows and Mac.
Also see chrome bug:
<a href="https://bugs.chromium.org/p/chromium/issues/detail?id=666384">https://bugs.chromium.org/p/chromium/issues/detail?id=666384</a></pre>
