Description Dave Airlie 2016-05-09 06:34:28 UTC 
I haven't tested this on other, but on haswell this test fails.

The test is pretty simple, it goes transform feedback 3 test, which does

vec4(0, 1, 2, 3), skip4, vec4(4, 5, 6, 7), nextbuffer, vec4(8, 9, 10, 11), skip4, vec4(12, 13, 14, 15)

it expects:
buffer0
0, 1, 2, 3, 0, 0, 0, 0, 4, 5, 6, 7
buffer1
8, 9, 10, 11, 0, 0, 0, 0, 12, 13, 14, 15

we get
buffer 0 is okay,
buffer 1 lacks the gap in the middle.

It runs correctly on llvmpipe.

Test passes for me on Haswell. Not sure if a Mesa change or a CTS change is responsible.
