I experience this issues as well on Linux Mint with Cinnamon.

It only happens on one of the screens. On my screenshot you can see how i dragged the window across.

My setup is:
Linux Mint 18 Cinnamon 64-bit
Cinnamon 3.0.7
Kernel 4.4.0-45-generic
Intel(R) HD Graphics 4600
Dell D3100 Dock
X.Org X Server 1.18.4

Edit:
After reboot it seems like both of the screens have the issue. Not sure what I did to make it work on one of them.
