[Bug] Linux connecting in material editor

Hi,

I have some problems with the 4.9 build for Linux.
The material editor is behaving really strange. Sometimes when i try to connect some notes the wire (and my mouse courser ) are jumping wild across the screen. Beside that i am also unable to copy and paste notes in the material editor. It fails with ctrl+c and ctrl+v as well as with the right click dialogs.

All these things were working in the older versions. The only change beside the new Unrealengine version is a new “sometimes” dual-monitor setup.

I set up the editor like all the other builds with no Errors or warnings.
My system:

Mint 17.2
Nvidia driver 355.06 with gtx 860m
Intel i7 4710HQ
8gb Ram

Dualmonitor setup

If someone needs more informations feel free to ask.

Maybe may description of the problem was not good enough :smiley:
