Wayland apps, specifically gnome-terminal, seem to adapt to DPI changes just fine.

It is the XWayland apps that seem to have the problem. For pure X sessions I've seen people recommend running at 4K all the time even on 1080p screens, using xrandr to scale the 4K to 1080p. That way everything is ready to jump to 4K on demand.

How does gnome-terminal adapt to DPI?

To adapt to a DPI change safely in font rendering would require that the font data structures get reinitialized.

I've thought about setting everything to 4K all the time but have not figured out how to do that yet. It would of course use a lot of unneeded CPU/GPU.

My current idea for a workable approach is to use a compromise font size for the UI, write a script to restart apps that have good session management and another script that changes the font-size in konsole via dbus.
