Line DX11 crash

Hi dear VVVV community;

I got a weird crash concerning line (DX11). When I create the node everything is alright but as soon I open the help patch vvvv freezes or crashes completely. I can’t see anything on tty because of the crash.
I use windows 7 64 bit with vvvv 32.1 64 bit on a laptop with an ATI card.
Has anyone experienced that ? All the other nodes seems to work fine.

Thanks in advance;

edit: there seems to be a thread here https://github.com/mrvux/dx11-vvvv/issues/159 about that particular issue
