Yeah same issue here, much worse performance than the XQuartz releases. Dragging objects, especially arrows, is extremely laggy and awful. I've moved to Affinity Designer for now, which is better in almost every way except that unfortunately it is not easy at all to add LaTeX equations. Also the UI looks somehow feels less native macOS-like than the XQuartz versions, they're still not even using NSOpenPanel which is a huge pet peeve for me
> Yes. This is related to GTK and is holding the macOS release back while Win/Linux graduate from beta. If you want to connect with the developers they can be found at: https://chat.inkscape.org/channel/team
So if you want to help resolve it, perhaps check there :)
