Bug report - Random window movement (no replies)

I'm just starting to use your software and so far, so good. It works quite well, congratulations and thanks.

Anyway, I'm experiencing a weird bug in Linux Mint 18 using Cinnamon desktop: When I try to move the main window of the program or any other, sometimes it moves randomly like if it lost track of actual mouse position. It happens from the beginning, just after installation.

Regards
