[Webkit-unassigned] [Bug 215141] Flickering on sedona.dev

--- Comment #15 from Dean Jackson <dino at apple.com> ---
For the black frames there is a call to

context.drawArrays(POINTS, 0, 4942);

that does not render anything. But that same call does render correctly on the non-black frames.

I think something is confused when the app switches framebuffers, which it does every frame. In fact, once the graph becomes stable, it doesn't appear to draw any geometry.
