I have no idea how to bisect mesa tbh. I'll look into it later and see if I can
manage.

Not sure if it's relevant, but this shows up along with latest mesa and those
Unity glitches.

I'm using oibaf's ppa with Ubuntu 14.04 and I can confirm that it's happening
as the OP reported. (Attaching my Xorg.log to help with the ticket)

Eric, any ideas? I haven't seen this myself yet, but several people have
bisected these problems to your commit above.

The only obvious semantic difference I can see before and after the patch is
that before it, all formats out of a group with at least one unsupported format
were converted, whereas after it, supported formats are always used directly,
even if some other related formats are not supported.

u_vbuf: Make sure all caps are initialized

Does this patch help? I think caps.user_vertex_buffers being randomly 1 could
explain the symptoms.
