<pre>A few observations:
- Pretty sure you want GL_TEXTURE_FETCH_BARRIER_BIT. Not that this matters for
nvc0.
- In addition to this always working on GM107, it *sometimes* works on my
GK208. Something about card state? Or something in compute insufficiently
initialized?
- I tried setting the DEPTH_TEXTURE bit in the TIC with no effect.
- The GM107 works just as effectively with both old- and new-style TIC formats.
- Throwing glFlush or glTextureBarrier into the mix made no difference, so it's
not a cache issue.
- Switching to DEPTH24 and DEPTH32F made no difference.</pre>
