General Display question

[Erik Soderquist]

james, to what versions does that apply? ie: how far back would he need
to go for vnc to pull data from elsewhere, and where would that be?
mostly idle curiosity....

Jason,

VNC Server grabs the pixel data back from the video card's buffer in the
current releases.  This means that if the video driver or card are
corrupting the buffer contents, then VNC will also see those corrupted
contents.
