That's just means that it works with your video card(s), but it can still crash with other/older cards. For example on the ShaderToy website ( https://www.shadertoy.com/browse https://www.shadertoy.com/browse ) I can always easily find examples that crashes WebGL in Chrome (and it's just slower or hangs in Firefox). Right on that first page there are shaders that makes WebGL crash on two different computers (one with an older NVIDIA card and one with just integrated so not the fastest ones). But it crashes only the WebGL part not the whole browser, so that's not so bad. Also it could be because Chrome sees WebGL code is running slow (due to slower cards and the complex shaders) and decides it's better to kill it, just like when there is an infinite loop in Flash or JavaScript the browsers shows a dialog to stop the code.
