OK,
I tracked this, I am answering myself for the record.
On my system, I had to recompile OSG.
It seems on left-shift-key release, Xorg sends a release event with a wrong
keysym (XK_ISO_Prev_Group instead of XK_Shift_L).
Same thing for right shift key. On release, the X11 keysym is
XK_ISO_Next_Group instead of XK_Shift_R.
So i remap these in OSG through the _extendedKeymap of GraphicsWindowX11.
I add the following remappings in GraphicsWindowX11.cpp of osgViewer:
_extendedKeymap[XK_ISO_Prev_Group] =
osgGA::GUIEventAdapter::KEY_Shift_L;
_extendedKeymap[XK_ISO_Next_Group] =
osgGA::GUIEventAdapter::KEY_Shift_R;
Not sure this is the correct solution, though. It works for me.
Maybe this concerns OSG people? Xorg people?
Cheers,
Sylvain.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
