> A lot of people keep saying this about X apps but anything written with GTK will be awful because (from what I understand) it’s just paints everything itself and then uses X11 to actually display what it draws. Plus if you run anything over the network like that GLX doesn’t work. I don't find that to be true, e.g. I've used pavucontrol (a GTK3 app) over the wifi X11 networking and it worked fine - the very nice thing with X11 networking is that it will use your client DPI for rendering / Xresources / etc... so you can have both lo-dpi and hi-dpi clients connecting to the same machine and it works for both without any configuration.
