Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Steps to reproduce the problem: We are working on an SDF (signed distance functions) based modeller at www.raysupreme.com. It uses a PBR based path tracer for rendering and requires WebGL v2. We, as many others I guess, have problems with crashes / long compile times of the rendering shaders. As the map() function inside the shader gets quite big with larger scenes, and this function is inside the path tracer loop, it looks like there is an aggressive loop unrolling going on during shader compilation. The attached test scene crashes Chrome but works fine In Firefox (although compilation time of the shader is about 15 seconds). I guess FF just "waits longer" for the shader compilation to finish while Chrome throws an exception after a few seconds. My questions: * Is there a way, or will there be a way, to disable loop unrolling during shader compilation ? We would happily sacrifice performance for being able to safely run the shader, this is non realtime rendering anyway. What is the expected behavior? No crash during shader compilation What went wrong? Shader compilation crashes probably due to aggressive loop unrolling (path tracer loop) Did this work before? N/A Does this work in other browsers? Yes Chrome version: 58.0.3029.110 Channel: stable OS Version: OS X 10.12.5 Flash Version:

Thanks for the report. I wasn't able to reproduce on the first try. Please provide the chrome://gpu on the affected system (copy+paste plain-text into a comment is best).

Chrome isn't performing any loop unrolling internally. See this code search result in ANGLE's shader translator: https://cs.chromium.org/search/?q=unroll+third_party/angle+package:%5Echromium$&type=cs The most that Chrome/ANGLE do is to hint to the Direct3D compiler on Windows not to unroll loops that contain discontinuous gradient operations. I also couldn't reproduce the reported failure, but it looked like the scene failed to load. There wasn't any error message, but the render was blank.

kbr: just a nit, the report is on Mac, so we would have to hint to the OpenGL compiler. (I don't know of any way to do that other than to do sneaky and possibly detrimental shader transformations.) When I tried to repro, I got a similar result to kbr, I think.

I think you don't load the house scene correctly. Hit the open project button in the toolbar and drag and drop the project file in the drop area. After that you should see the house in the preview. Now click render to render and it would hang. Beta testers also see the bug on windows. It has to be loop related. When I hncomment the path tracer iteration loop it works. When I add the loop with just a depth of 1 it hangs during compilation.

kainino: Understood that the report is on macOS. There are no such hints in the GLSL language. Whatever problems are occurring on macOS are almost surely happening in the actual OpenGL driver's shader compilation. Submitter: you're right, I was loading the scene incorrectly. I can reproduce the failure now. Attached is a trace from about:tracing. It looks like the shader's compilation took so long that the GPU process's watchdog killed and restarted the process. I doubt there's anything the browser can automatically do to make this work. For reference, ShaderToy's shaders are some of the most complex that are encountered, and the most complex shaders there don't work on all hardware. I suggest that you look into changing the form of your shaders to do either one iteration, or a fixed number of iterations and manually unroll them, and store intermediate results into a floating-point texture. Then feed that texture into the next iteration, so that instead of looping in the shader, you issue a draw call to perform each iteration, or a few iterations of that shader. Once you figure out a construct that will work for your application we can see if the solution will generalize.

Just another datapoint: The render works for me now that I'm also loading the scene correctly. However, there was no crash. This is on MacBook Air, Intel HD 6000. This further implies that it's probably an issue in the (hardware-specific) shader compiler.

Ok. I understand re OpenGL. However the reason I reported the issue here is that Firefox compiles this scene fine on all computers. Even the ones Chrome hangs on ... I guess it just awaits longer for OpenGL to finish compilation. For us it's important that Chromium works because we use it to build the desktop versions ...

Submitter: I see. In that case you can pass the command line option --disable-gpu-watchdog to Chromium for your bundled application. I just tried this with Chrome Canary and it makes that scene render successfully on my MacBook Pro with NVIDIA GPU.

Thanks for the suggestions for the gpu watchdog and also to unlooop the path tracer. We will try that. However, why is Firefox not hanging with this scene ? Does it disable the gpu watchdog by default ? Btw; is there a cli option to change the default antialiasing for webgl ? Fonts look blurry as Chrome only does 4x4 AA by default.

Chrome's and Firefox's graphics stacks are entirely different. Firefox doesn't have a separate GPU process and consequently I don't think they have the concept of a GPU watchdog timeout in the browser. Chrome has had one for years to enforce a better user experience even in the face of problematic content, or DoS attempts. Right now there isn't a way in the WeBGL spec to change the antialiasing parameters of the default back buffer. Could you please file a new bug about that and provide a standalone test case? I'm not sure how you're rendering your fonts but suspect that pre-generating high-quality antialiased texture atlases should work well. Closing this report as WontFix. I don't think it's a good idea to increase the GPU watchdog timeout in response to this report.
