I have a requestAnimationFrame loop which renders some webGL. It seems that it does this very fast, but i still see these dropped frames in the profile. It doesnt always seem to align, with this “Task” that i have selected but i wonder if it is related.

Why are these requestAnimationFrames spaced out in this way if they take such a short time to execute?

Within these 4 visible frames, i should see 4 of these stacks not 3?

What is preventing the red frame to the right from having a requestAnimationFrame execute?
