This application uses a geometry shader, and runs without crashing, but there
are graphics artifacts, see geometry.0000001176.png and
geometry.0000001644.png:

Source code for the application can be found here:

It doesn't work exactly as is with the upstream source code, due to mismatching
layouts between vert/geom/frag shader, but adding this to all shaders makes it
run:
layout(std140) uniform;

Let me know if a tarball with a working source code would help debugging or if
the apitrace suffices.

I did an apitrace, and rerun it using llvmpipe forced to 3.3, and there are no
artifacts there, see geometry.0000001176.good.png:
