From: Roland Scheidegger <srol...@vmware.com>
ARB_ubo requires 12 UBOs (per stage) at least, but this limit has been
raised by GL 4.3 to 14, so don't advertize GL 4.3 without it (only checking
the vertex stage since all drivers probably have the same limit anyway for
other stages). (piglit has minmax tests for that kind of thing, but they go
only up to 3.3, so this won't really be noticed.)
I think this currently should not affect any driver - r600 until very
recently only supported 12 but now advertizes 14 too.
