Moving DockNodes does not work under Linux

[xylo]

I discovered a strange behavior when I try to drag a DockNode. First, a window is created and dragged with the mouse movement (which I expect to be intended). But after around 100 ms this window get stuck. It does not follow the mouse anymore and it does not respond to any event. I cannot even close the extracted window anymore and it keeps staying on top of all windows when I switch to another application window.

My system is a 64 bit Linux system with a Kernel 3.13.0-100-generic running in a virtual machine (via VirtualBox).
Here's my java version:

java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

During one of my tests I got also this exception, but somehow I doubt that it's related since it appeared only once:

This might be a more general JavaFX issues as FxDock has the same problem. DockFX also suffers from this, but there the window starts moving again for a second every five seconds are so.
Using OpenJDK 1.8.0.112 on Arch Linux (4.8.13), with an intel integrated GPU (but I thing I also saw this with my nvidia GPU).

I also have this issue. I was surprised, as on the Windows there is no problem.

Linux Mint 18.1 Serena
kernel 4.4.0-53-generic

java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

Anything new about this issue?
AnchorFx moving dock functionally just doesn't work under linux.
