Chrome headless lost WebGL support on MacOS

[elalish]

Starting with Chrome 109, WebGL contexts can no longer be created in my Karma tests, meaning I can no longer run my tests locally. It appears to be because Chrome no longer supports software rendering on Arm-based macbooks, so the work-around is to enable the GPU instead: https://bugs.chromium.org/p/chromium/issues/detail?id=1407025#c9

I tried adding the indicated flags, but it's still not working because the launcher is also adding --disable-gpu:

karma-chrome-launcher/index.js

Line 172 in 5f70a76

'--disable-gpu',

Is there a reason the GPU should be disabled in headless mode? Is there a workaround for this, or can we remove this flag?

Getting Same Error. Can we expect the fix asap?

Do you guys have a workaround? maybe patch-package? How did you solve this, I ran into this problem just now...

Karma got deprecated since I opened this, so I ended up switching to the modern web test runner instead. It's working great! My PR looks huge, but that was mostly other cleanup; you can see the new config here.

[HarelM]

So you switched from karma to playwright? Can you link to the karma deprecation article? Or are you saying that only this plugin got deprecated?

THANKS!!

If you don't have a hard requirement for Chrome Headless, using regular Chrome will not have the WebGL issue.

I just did that (granted it uses more memory, but at least I can run my unit tests without switching unit test frameworks or manually patching a file inside node_modules/)
