@neil.hansen.31 I think the ones that print in the repl are ones that get thrown on a background thread.

The ones that create a new buffer are the errors that are thrown in the repl thread.

(At leaset, this explains the pattern I’ve seen)

@fiddlerwoaroof Oh, that makes a lot of sense, thanks for the clear explanation. It has indeed been the Quil-specific drawing functions that draw those errors, of course those would be on another thread. How does everyone else normally deal with this? There must be another solution to analyzing background thread errors. Looking at the REPL printouts is too painful for error messages as verbose as Clojure's.
