None of these apps feel quite right though. Even Atom still doesn't do DPI scaling properly. VSCode does, but opening 2 panes sometimes causes it to break.
Sample problem (left pane blurry, right pane sharp - view at 1:1 scale on ~100dpi screen to notice it easiest, but it's quite visible to me with scaling even): https://i.imgur.com/Ju0UK2K.png
