I use a GUI written with Gtk and ImageView from time to time and I can confirm that the workaround proposed by @tim.holy improves the experience. I wouldn’t say it fixes it 100% because occasionally I see stutters, but it’s better. Just modify according to the comment, build Gtk and give it a try.
For my is not the some problem, VS and ATOM are not siimlar.
Just use only REPL Julia Studio ,Atom, all are slow on win !
I checked Linux, is the same , Win7 and Julia on Vbox or just on HD is fastest!
Win10 is not system … it is some like jam
