        <pre>If I run two instances of this python pyglet program, the 2nd instance is
frozen until I stop the first one (same with other apps).

Program that freezes (needs python and pyglet) - is in this directory
<a href="https://github.com/stuaxo/graphics-playground/tree/master/daily7">https://github.com/stuaxo/graphics-playground/tree/master/daily7</a>


My system is a laptop with Optimus, and running with DRI_PRIME=1 the program
doesn't freeze.


I've recently enabled SNA, this hasn't fixed the freezing, but has made
DRI_PRIME apps work OK (about half used to start with a black window until
resized, they now work - glxgears worked, glxspheres was black).


Running oibaf drivers, with Nouveau on the nvidia half.
