<pre>There are some differences on the results of those test if you run then inside xvfb or on the native display (Xorg/X11 in my case with Intel GPU. glxinfo: <a href="http://sprunge.us/WBjL">http://sprunge.us/WBjL</a> ). You can run them on the native display by passing --display-server=xorg to the script run-webkit-tests.
Differences between --display-server=xorg and --display-server=xvfb :
* webgl/1.0.2/conformance/textures/texture-mips.html and webgl/1.0.2/conformance/textures/texture-npot.html pass on native Xorg but fail on Xvfb.
* webgl/1.0.3/conformance/extensions/webgl-draw-buffers.html crashes on Xvfb (crash log: <a href="http://sprunge.us/jTBV">http://sprunge.us/jTBV</a> ) but fails (without crash) on native Xorg.
* fast/canvas/webgl/drawingbuffer-test.html fast/canvas/webgl/webgl-depth-texture.html pass on Xvfb but fail on native Xorg.
* More tests timeout or are slow on native Xorg.</pre>
