My Question

I'm wondering the same! Would be nice to be able to change the icon. Right now, at least under Ubuntu 20.04 with Open3D 0.17.0, no icon at all is shown, which makes it hard to distinguish the application in the launcher from other running programs. In my case, I am using the modern GUI based on open3d.visualization.gui.Window.

At a first glance, it looks like a call to glfwSetWindowIcon() should be added somewhere in cpp/open3d/visualization/gui/GLFWWindowSystem.cpp. The problem may be that according to the GLFW documentation (under "Remarks"), this will not work under MacOS or using the Wayland display protocol (e.g. under Ubuntu 22.04), where instead the icon is automatically inherited from the application's desktop file.

The discussion here provides some hints at least for Ubuntu 20: https://discourse.glfw.org/t/taskbar-icon-in-linux-gnome-3-38-3-ubuntu-20-10/1769

Hi. Would be nice if this functionality existed in Python too.
