Support for WebGL when running on Lambda

[wmdmark]

I'm trying to grab a screenshot of a webgl rendered UI and it doesn't appear to work on the when running on the example Lambda playground. Here's an example playground trying to screenshot a webgl map: example

An the image I get (note error message):

I assume this is because Chrome is being launched with the ---disable-gpu flag set. Is there a way to override this behavior?

@pklingem I've seen that but it actually works just fine w/out that flag. Is there any way to disable it currently?

Hi @wmdmark — Outside of the Lambda context, the --disable-gpu is not set. However, currently within the Lambda contexts, --disable-gpu is required or Chrome won't run correctly. This may be resolved soon with some coming updates upstream in serverless-chrome.

I just wanted to say that I ran into the same issue. If anyone has a workaround, that would be greatly appreciated.
