This thing is good for some apps like Android Studio, but bad for other apps like Krita, which has no in-built scaling option. As far as I have researched, there is NO WAY to customise this setting per app. But is there at least a way to change this setting more easily with using script or something? That is, I want to change the setting to “Scaled by the system” automatically before launching Krita.
If there is a config file that gets written to maybe you can edit that and change it that way.
Yes, switch from Wayland back to X11
