I agree with other posters that Fractional Scaling in 19.04 is useless. It is useless in particular if you want to have one (bigger) monitor at 100% and the laptop monitor at 125%, a configuration that works particularly well in Windows. But my argument is that FS is not hardware accelerated, it overheats the laptop and even then makes everything run extremely slowly. You can't watch a Youtube video in any of the screens, it becomes a PowerPoint slideshow.
