Maybe you want to talk to Duncan (CC'ed) about this, he just had a thread
about rgl and event loop issues on r-package-devel.

As earlier in this (or the preceding) thread, I am not yet _fully_ convinced
that what you are experiencing are in fact an Rcpp issue.  There is something
(a lot, actually) to be said about _minimally complete verifiable examples_.
As Rcpp maintainer, I am not sure if bringing rgl (a fine package, but also
"complicated" / "ambitious") in does still satisfy "minimally".
