Not working #75

Closed jack1232 closed 3 years ago

jack1232 commented 3 years ago

The samples worked few days ago. However, after updating Chrome Canary to Version 89.0.4387.3 (Official Build) canary (64-bit), suddenly, none of the samples work with the following error (same for all samples):

TypeError: Cannot read property 'requestDevice' of null at rotatingCube-6f3dd6430b02cabc591c.js:1 at l (1be8be7c52e2349f8660686032d2042ae0b6bb9e.08d4626ed8f6bcf6d877.js:1) at Generator._invoke (1be8be7c52e2349f8660686032d2042ae0b6bb9e.08d4626ed8f6bcf6d877.js:1) at Generator.next (1be8be7c52e2349f8660686032d2042ae0b6bb9e.08d4626ed8f6bcf6d877.js:1) at r (5e050aff538434ccde2cc97438110cf81079bf6a.910cf116a21df707471b.js:1) at s (5e050aff538434ccde2cc97438110cf81079bf6a.910cf116a21df707471b.js:1)

it seems that it can get webgpu context but not the device.

Hm, what OS are you on? I just tested with 89.0.4387.3 (Official Build) canary (x86_64) on Mac and it works ok.

jack1232 commented 3 years ago

windows 10.

If you have --enable-unsafe-webgpu enabled and await navigator.gpu.requestAdapter() is resolving to null (can just check that in a dev tools console),

then could you please file a bug on crbug.com and attach the contents of about://gpu

jack1232 commented 3 years ago

Yes, the '--enable-unsafe-webgpu' flag is enabled. and find 'await navigator.gpu.requestAdapter()' is indeed resolving to null in the console.

OK, I will file a bug report there.

Chromium bug.

An origin trial token is needed on websites that wish to display WebGPU content to users. A token can be created here.

Note WebGPU is shipping ungated in Chrome 113 (EDIT: on Mac/Windows and some ChromeOS devices), releasing May 2 (and the origin trial has been removed since it doesn't do anything anymore). https://chromiumdash.appspot.com/schedule

liudonghua123 commented 1 year ago

Can't wait to use the new Chrome 113. ✌️

kainino0x commented 1 year ago

You can use it already in the Beta channel (or Chrome 114 in the Dev/Canary channels). 🙂

liudonghua123 commented 1 year ago

I would like to use the stable channel, or I will get two version of chrome. Wait for May 2 to update my exist chrome.
