Hi there!
I came across the bug that at 1600x900 and with an interface scaling smaller than 1.0 there is a bug that the UI won't stay where it should. E.g. the health bars are dragging over the screen. For better imagination i made some screenshots (I dont know how exactly i can manage to provide them inline so here are the links) :
Interface_scale_0.8_no.2 Interface_scale_0.8
I ran it with DX12 in windowed mode and were not able to set the interface scaling to 1.0
To my specs:
AMD R9 270X
Intel i5-4590
Screen 1600x1200
8 GB RAM
Sincerely
Darkflame
