Took quite a bit of time.. but not as much as I had feared. I knew about
git bisect, but didn't know quite how easy it was to test a new mesa
version. (I had feared the kernel + 2D driver bits might need to be
changed in sync).
After a bit of a false lead, I finally tracked the behaviour change to:

Hope this helps!
FWIW, this was my (manual) bisect test script:
#!/bin/sh
make clean
./autogen.sh
./configure --disable-glut --disable-glw --disable-glu --disable-egl
--disable-gallium --with-dri-drivers=i965
make -j2 -s
