Using XFCE 4.14-r2 (Gentoo) and things are okish with Intel GPU (Lenovo P71, 17' 4k panel). But I did not use the option "Window Scaling" (currently set to 1x) instead I changed in the Fonts-tab the "Custom DPI settings" setting it to 192.
The only problem that I have left is with Google Chrome & Vinagre: whenever I move the cursor inside their windows it stops being scaled up (therefore it becomes tiny). Used to work fine, changed during some recent update :(
