--- Comment #4 from Miguel Gomez <magomez at igalia.com> ---
The problem here is that the webgl frames are rendered faster than they are composited.
As we only have 2 buffers in GraphicsContext3D to hold the rendered frames, sometimes a buffer is reused for rendering when it hasn't been composited yet (or while it's being composited), and this causes the flickering.

I'll attach a patch that fixes this by using one extra buffer to hold the renderings. This removes the flicker issues.

But at some point we should add a general solution (also for the acc canvas) that somehow blocks the renderings when there are no buffers available.
