It is exclusive, but not to the first app it seems. The code to get hyperZ
ownership is in the buffer clearing function and I see it with my bare eyes
right now so I think not only the first app can get it, but if you exit that
automatically some of the next one (that gets clear called first).

> It worked fine here, too.

Is there any indicator to look for? Like shader files on disk at some place=
s or
near the runned binary or current dir or whatever with this or that name?
