Graphics issue when creating vignettes with high dpi setting

[RS-eco]

Adding a dpi setting to the knitr::chunk_options()

knitr::opts_chunk$set(
  dpi=300,
  collapse = TRUE,
  comment = "#>"
)

of any vignette, for example: annotation.Rmd of the patchwork package, results in weird formatted multipanel figures, when using patchwork. I am not sure if this is a bug or a result from changes in RStudio and R with R version 4.1.0 and RStudio version 1.4.17.17.
