I cannot get ProfileView.jl to work on Wayland because of a shared library incompatibility. I will file a bug report as soon as I isolate the problem, but in the meantime I am looking for a replacement/alternative.

in the end because it has a nice user interface. Still don’t know how (if?) I can show argument type information with it though.
