vc_screenbuf is accessed through screenbuf macro from console_macros.h.
It is very hard to find anything in console.c. I use simple rule:
all X variables you see in function are vc_X members of vt struct unless
you see definition of X on your screen.

Well, i did search for screenbuf and not vc_screenbuf, and i did find the macros.

I did not find any reference in anything excepth vgacon_switch and vgacon_save_screen.

Also :

is vc_screenbuf still part of the framebuffer memory, i thought it was some other main memory, a ...

Mmm, i will have to look more at it, thanks for the info thpugh.

BAsically, i am now sure that i copy the right data to the screenbuf (well for the character data, i just use empty attributes, is that ok for now ?, where can i find the attribute format ?).

But it seems the problem is when copying the stuff back to the screen that something goes wrong.

I suspect that it is not the correct data (the one in screenbuf) that is taken or something like that.

But then, maybe i am worng (well most probably i am wrong).
