Multi-display fbo texture sharing between contexts

I use multiple windows on my program, so I share the context with each additionnal openGL output window,

on a multi display machine,
pbo textures are shared well on the first screen, ie pbo textures created in one context are useable by other contexts.
but when I move the window on the secondary display it is not updated (the texture is always the same).
“regular” textures and pbuffers are working well.

I’m using a GF7800 gtx with 84.10 drivers

I tried to look in the driver settings, and by changing the “Hardware acceleration” to “Multidisplay compatibility mode” instead of “Multidisplay performance mode” and it works.

Can someone explain what is the exact difference between these two modes ?

And confirm it is a bug ?
