Incorrect fonts with RStudio Server in docker

[eldenvo]

I am running R 4.3.1 in a docker (rocker/tidyverse), with RStudio Server 2023.06.0

Having some issues getting ggplot outputs with the correct font.

I have installed google fonts and loaded them via extrafont but I do not get the same outputs as I do from my windows pc.

Using the 'Alata' font as an example, and "Alata" %in% fonts() returns TRUE across both instances.

library(tidyverse)
library(extrafont)
library(ragg)

as_tibble(mtcars, rownames = "car") %>%
  slice(1:10) %>%
  ggplot(aes(x = mpg, y = car)) +
  geom_col(alpha = 0.4) +
  geom_text(aes(x = 1, label = car), hjust = 0,
            family = "Alata") +
  theme(axis.text.y = element_blank())

ggsave("test.png", height = 12, width = 9, dpi = 300, device = agg_png)

The desired image (as I get on windows) is:

But in the plot viewer on RStudio Server I get:

And the ggsave output from RStudio Server is:

What gives? extrafont can see the correct font is installed, but it doesn't get used properly by ggplot or ggsave in my docker instance?
