Terminal state isn't cleared on slide change with some effects

explosions and stars do this, but matrix works fine.

I suspect that this is related to #11 . The Matrix effect relies on the Scene being configured to leave the Screen as is before starting the Effect, thus slowly wiping what was previously on the Screen. If I were you I'd consider it as one of your transitions rather than a bug in the use of effects.

Thanks for the tip! I didn't know about that, I'll look more deeply into how some effects work.

Hello!
Issue is also actual for clearing after codio. For instance second slide from following markdown

---

![codio](codio.yml)

---

```
{
    "some_key": "some_value",
    "another_key": "another_value"
}
```

contains both codio and code blocks:

@perminovs I'm able to reproduce this. I'll look into a fix soon.
