Ok, looks like that's caused by glamor re-using FBOs that were too large
for tile pixmaps. Oddly, the texture fetch doesn't work like you'd want
in that case.
I've added a patch to keep glamor from ever using over-sized FBOs. We'll
probably want to re-enable that optimization at some point in the future
as it does tend to save a ton of allocation overhead, but we'll need to
be careful to only use it when the object isn't being used as a texture
source. I wonder how many other things this will fix...

I've fixed those commits so that you should be able to bisect through
them and find the broken bits.
