Oh, I hadn't realized that was still a todo. In the meantime, what's the
implication of shipping without it? (I.e. in which threat model are
users vulnerable without it?) Malicious userspace process snooping on
other framebuffers (on X11, they could do that anyway...)? Malicious
userspace actually interfering with operation of other processes (is
this really exploitable or just a theoretical concern)? Malicious 3D
apps breaking out of the sandbox (i.e. WebGL) via a driver bug and
snooping on other processes?
