<pre>OH! DUH!
apitrace: warning: glMapBufferRange: MAP_COHERENT_BIT|MAP_WRITE_BIT unsupported

Right, so you need to run this with
MESA_EXTENSION_OVERRIDE=-GL_ARB_buffer_storage. Or find some way to force
glamor to disable it. apitrace doesn't like it. I'm sure that's why the
textures are garbage.</pre>
