--- Comment #1 from Roland Scheidegger <sroland@vmware.com> ---
Looks like pretty much the same issue as 105139 to me.
Somehow a depth/stencil format texture gets attached as a color attachment (I
can't think of any reason why anyone would even try that...), and if that gets
through all bets are off.
Though the framebuffer completeness code does have code for checking color/ds
format mismatch, so no idea how it could happen.
