matteo: can we get this fixed for 53? Do we need to back out bug 1312103 from 53, or is this something we can live with

Too late for 53. We could still take a patch for 54 though.

Unfortunately we cannot do much. This is due APZ, and elements positioned fixed (or sticky when they behaves like fixed). I mitigate a bit the effects in bug 1351081, but we cannot remove totally the effect, because the scrolling is happening in a different process.
