Steps to reproduce:
I tried drawing my own canvas with javascript. I then looked at the opencv.js pages to see if any of their canvases loaded.
Actual results:
Both showed a black box, the data is being passed to the canvas properly as it loads in chromium browsers.
Expected results:
It should have drawn the canvas or rendered something in the canvas element.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: Canvas2D' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can you link to or upload the simplest example canvas that you've tried that hasn't worked?
Can you upload a copy of your about:support?

I am not sure what is different today but I have not been able to reproduce the bug. I will send my about:support regardless, sorry for the confusion.
Link to initial example site : https://docs.opencv.org/3.4/dd/d6a/tutorial_js_filtering.html
