I've encountered the same issue on Manjaro after a recent system update (update to Manjaro 21.2.1), using RStudio official binaries.
I've opened a separate thread but just wanted to add that doing this
maybe it would be worth to move ~/.config/rstudio and ~/.local/share/rstudio out of the way for a moment to ensure you don't have any left-over legacy configuration in there
didn't help. On the other hand, changing to software rendering seems to have solved the problem for me.
