I've seen this recently as well. I've done a bunch of updating recently
(R to 4.1.0, chromote to the latest devel version, Chrome to a new
release) and it's probably related to one of those, but I'm not sure
which. What I've found is that the lockup occurs in chromote, and
that's suspicious but not necessarily proof of the source of the problem.
Do you have the same problems if you install the older file
https://github.com/dmurdoch/drat/blob/gh-pages/src/contrib/chromote_0.0.0.9002.tar.gz
?

Hi all,

I have problems using snapshot3d from rgl while trying to render an R
Markdown page. I want to do this to capture static snapshots of an
interactive widget on the page. I had this working with an earlier
version of R (sorry, forgot which), but this now hangs indefinitely at
the snapshot3d call.
Should I expect this to work? I can successfully create a snapshot
from an interactive R session with either webshot=TRUE or FALSE, just
not from within my R Markdown build.
I have created a simple reproducer, which I attempt to build using:
library(rmarkdown)
rmarkdown::render("reproducer.Rmd")
where the contents of reproducer.Rmd are:
$ cat reproducer.Rmd
---
title: "rgl test"
output:
html_document:
toc: true
toc_float:
toc_collapsed: true
---
```{r, setup, echo=FALSE}
library(rgl)
library(knitr)
knitr::knit_hooks$set(webgl = hook_webgl)
```
### Insert rgl figure
Test
```{r, webgl=TRUE, echo=FALSE}
with(iris, plot3d(Sepal.Length, Sepal.Width, Petal.Length,
type="s", col=as.numeric(Species)))
snapshot3d("foo.png")
rglwidget()
rgl.close()
```
