--- Comment #11 from Kimmo Kinnunen <kkinnunen at apple.com> ---
At least the attached minimal webgl camera pipeline test-case uses
`PIPELINE_SIZE = 10`. This would trigger bug 203148.

So on iOS, the frame rate would typically default to 30fps, and rAF is 60FPS, so from the get-go the pipeline is filled with 5 identical textures.

If you want to necessarily use multiple textures, one approach to test would be to upload 1 pixel sized sub image to each texture before uploading the video element. This would clear the buggy cache. I know it's a bit inconvenient and, probably it is quite a bit extra overhead.
