Just poked the Khronos folks and sent a patch for mesa.

Gents, don't be shy to report and/or send patches when you see
something odd with mesa.
Patching it in weston is ok for short term solution but (mesa/Khronos)
breaking things and expecting everyone to add workarounds in their
code is a serious no-go.
