So far I've seen glxgears fullscreen (full HD) does not manage the normal 60fps
that EXA does. With glamor it is like 30fps. But I need to determine if it
isn't caused by Tearfree.

I am not able to ssh to the machine and run a tracer in 10 seconds ;)

That would require upgrading the whole distro. But I have that in planning in
the next 1-2 months.

Yes it does. I've removed these non-default options but the hangs are back
(default switched from glamor to exa again).</pre>
