Event Timeline

Blender 2.79 behaves the same.

I'm guessing this is working as intended, even though it does seem a bit odd.

Can anyone confirm?

@Sebastian Parborg (zeddb), this indeed sounds like an intended behavior. The segments gets tinted down when they are adjacent to the hidden keys. This seems to be missing in 2.80, but is something which shouldn't be hard to bring back i think. This is up to the draw manager department i think.

P.S. There is an assert failure in debug mode when hitting H in 2.8.

Sebastian Parborg (zeddb) lowered the priority of this task from 90 to Normal.

@Clément Foucault (fclem) seems like the decision is up to you.

Richard Antalik (ISS) changed the subtype of this task from "Report" to "Known Issue".
