Windows 8.1 strange screen scaling

i was setting up my new monitor and i found out this, when i have no scaling, this is how it looks when taking a screenshot

picture resolution: 6000x2160

and with scaling this is what happens

random empty space, picture resolution: 9000x2880

so far i've seen it affect steam chat windows...when moved from the middle screen to right...it jumps to the black...unseen space until dragged back to right

i also suspect this is causing my hydra grid's "edit grid" not functioning properly, i can only edit screen 1

is this a bug or just some extreme hack by microsoft to make things look right?
