No problem, I've pushed with Pekka's ack in the meantime. Please reopen if this
is still broken for you later. Thanks for the really detailed report!

I've been looking at this over the past couple of days, but haven't quite been
able to figure it out. Hopefully I can crack it today.

I.e. is there any reason why Daniel's revert should not be reverted?

Ok, as it happens on HSW, BDW & SKL, I would say that it's a generic problem.  

Is there any Mesa driver which non-vsynched frame updates are not broken by the
indicated Mesa commit?

Yes! I just installed Mesa git master and using Weston git master with your
delay patch, and it produces a mighty glitchy animation indeed.

I am on "GL renderer: Mesa DRI Intel(R) Haswell Desktop".
