I have the following code for a Quarto document:
---
title: "Any stuff"
date: 10/12/23
date-format: long
format:
beamer:
aspectratio: 169
jupyter: python3
pdf-engine: xelatex
highlight-style: atom-one
code-block-bg: true
code-block-border-left: "#31BAE9"
code-line-numbers: true
---
## First slide
- Some stuff
- more stuff
## Slide with code
```{python}
#| echo: true
import numpy as np
x = np.array([1,2,3])
y = x + 5
print("Hello, world")
```
No matter what I do, the code is printed against the white background of Beamer. It seems that Quarto is ignoring my command, although it throws no error:
