Yes.

I am using Manjaro Linux/XFCE.
A 3840x2160 above a 2650x1440 display.

I must add that the clipping occurs on from approx 1440 to everything below. 
I mean that for example
- If I try to select text with the mouse in a full height page, the selection
mark (inverted text) stops at approx 1440)
- If I do this in the lower display (2650x1440), I cannot select any text, I
cannot open any menu, with the mouse
- if I try to open a menu with the keyboard (ie alt+F), it works, but the menu
content is black

(I added a screenshot)

Thanks
