I've tried looking a bit into this at one point and my understanding is that it's more a toolkit issue than an app issue.
QT has an option to adapt the size of the widgets according to the reported screen resolution, which seems to kind of work. I don't use that many QT apps, so not sure how this turns out in practice.
However, GTK just doesn't care.
All this is on X11, I hear the situation is somewhat better on Wayland.
I'd guess in Wayland the compositor would be responsible for handling such issues.
I could readily see different filter profiles for different applications. Some of which render, and take input ques, at scaled resolutions.
What I hate a LOT more are games and applications that make any sort of connection between Pixel Aspect Ratio and a display resolution.
And for the niche case where you have a big disparity in DPIs of multiple displays + apps that can't adapt to DPI on the fly, scaling up is surely the wrong solution, you should be scaling down no the smaller screen.
