Well, the way scaling works on X is that we set a global value for the scale factor, and all apps just render that much larger. It is impossible for an X app to render at two sizes for windows that stradle monitors, and it is very hard to reliably and race-freely track what output your window is and dynamically resize the geometry as it moves around. Not to mention the many display-global options X has, such as mouse acceleration, pointer size, etc, that would be wrong in a hidpi multi-monitor situation. I wouldn't say it is impossible to fix this by introducing X extensions as needed, but this will be a major amount of work. _______________________________________________ desktop-devel-list mailing list desktop-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/desktop-devel-list
