Thank you for the report!

I can see some flashing on Intel. It's not yet clear to me if it's a test-case issue or implementation issue. The test case seems to create green textures.

It would be helpful if you would simplify the test-case. With a quick glance, I have hard time understanding where the video frame is being draw to webgl -- in main context or in worker.
If only possible, please remove:
 - any extra unnecessary files
 - any unneccessary variables, functions and codepaths: use_sub/use_draw, 2d context related code, etc.
 - any extra unneccessary communication between workers
 - if workers are not needed to reproduce the issue, please remove them, too

This would very much help me to address the issue.
