Parallax background transition "jumpy"

[ericthomas1]

Hello,

I've created a Parallax background image with this frontmatter:

---
parallaxBackgroundImage : "../assets/images/test.jpg"
parallaxBackgroundSize: 2400px 1000px
parallaxBackgroundHorizontal: 50
transitionSpeed: "slow"
---

Unfortunately, when I transition to the next slide, the parallax effect "jumps" the 50 pixels I have for the parallaxBackgroundHorizontal setting.

Is there a setting to make this smooth/slower?

Thank you

It seems that all backgroundTranstions are broken.
so this affects both the parallax and slides with background transitions

i suspect it has to do with some race condition maybe or caching or events. because sometimes the first transition between first and second slide may work, but after history is updated or has is added to the url it is not transitioning anymore. (have tried all combos of history and hash also)

the background animations in demo https://raw.githubusercontent.com/evilz/vscode-reveal/master/sample.md are not transitioning. Neither does video backgrounds start playing.

i noticed that if a slide has data-background="#000" for instance,
it adds a bunch of null values to a property called data-background-hash

<div class="slide-background has-dark-background present" data-background-hash="#000nullnullnullnullnullnullnullnullnullnull" style="background: rgb(0, 0, 0); display: block;" data-loaded="true"><div class="slide-background-content"></div></div>
