Hi,
I have noticed that I always get a segmentation fault if I use the openGL
versions of the sinks. This seems to be dependent on the graphics chipset, I
have two computers both with Intel G965.
The segfault can be avoided with LIBGL_ALWAYS_INDIRECT=1, eg,
$> LIBGL_ALWAYS_INDIRECT=1 usrp_oscope.py
Although this slows things down a little bit, it should still be faster than
pure software rendering.
I would be interested in reports from other people, especially which
chipsets/drivers segfault and which dont.
Stefan
