Don't know about the other links you've posted, but for photocraft the vast majority of those issues are from the engine that process the image itself, not about the GUI. In fact, as far as I can tell, none of the artcraft apps are that complex in terms of GUI to be slow down by any choice of GUI framework really. There could be performance differences between them, yes, but not so much.

You do realize that saying the PhotoCraft backend is also slow and buggy isn't helping your case, right?

		Why not? If the raw renderer has an unoptimsied denoise algorithm, what has that got to do with egui? They seem to be edge cases of building extremely complicated renderers (that handle varied user files/scenes) in a very short time. The projects are weeks old. The original app's renderers were built and optimised over decades against user files. I would also assume the central renderer is a 3d surface, not egui. Generally to the contrary, I was surprised how snappy their UIs feel in normal usage compared to the apps they're replacing.
