Steps to reproduce:

Nothing in particular except to update from Firefox 91.4.0esr to Firefox 94. Add to that since the Firefox 72 version I still have a problem with the webgl, for example the page https://webglsamples.org/aquarium/aquarium.html does not display anything but with other browsers and on the same machine everything works fine.

Actual results:

1 - webgl does not work
2 - artefacts on the web page

The Bugbug bot thinks this bug should belong to the 'Core::Canvas: WebGL' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hi,
I have attached the file "console-export" when I open the webglsamples page "Aquarium" and the page "about:support". For information, there was no change also with the version 95 however for the artifacts it disappeared.

The severity field is not set for this bug.
:jgilbert, could you have a look please?

For more information, please visit auto_nag documentation.

The artifact issue would be a problem with WebRender, so you should file a bug under WebRender if you're still having any trouble with that.

This is a known-troublesome driver/gpu, unfortunately.
The error in the console is from here:
https://searchfox.org/mozilla-central/source/dom/canvas/WebGLContext.cpp#848

Unfortunately this can fail for a ton of different reasons.
The only way to know more is to have one of our devs catch it in a debugger, or to provide you a custom build that can give us more insight here.

Hi Kelsey Gilbert,
Thank you for your feedback, as you suggested I have changed the ticket.

I wish you an excellent day.

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
