Text in graph view is hard to read when zoomed out

Even with ‘text fade threshold’ fully enabled, it is hard to read the text in graph view when zoomed out. It appears pixellated. (See picture). This presents a functional problem as I am often working with large graphs and I would like to see as many nodes as possible at once.

Is this a bug, or is it something on my end (do I need to change the font?) — help!
