Wires broken when displaying in KiCAD

Hi,

wires broken when displaying in OpenGL mode. Because of what it could be?

KiCAD version 4.0.1 Stable, Windows 7 x64.

Hi,
That is a (know?) bug with the OpenGL mode.
Would you like to rise a bug for it at:

please list there your graphic board and drivers version.
I saw that before but I was thinking that it was already fixed…
