<pre>More details:
* it works if I use a fixed guardband size of (-1,1,-1,1), which I think
consists to align the guardband size on the viewport size.
* it also works, if a use the top level window size (1024,717) as the gb_size
value in the function brw_calculate_guardband_size(), instead of
(8192,8192). Moreover, it hangs when I choose a gb_size value that is greater
than 718 in the computation of ss_gb_ymin and ss_gb_ymax (and only in the
y-range) in this same function. Of course if a gb_size lower than 717 is used,
gb clipping artifacts become visible, but it doesn't hang.
If needed I can provide a trace of the params used when
brw_calculate_guardband_size() is called.</pre>
