rendering on i965/skylake

Can't say that I agree. Attached is a screenshot from the same place in the
game, with the same settings on i965/Skylake, no texture bug. Software
rendering with llvmpipe is likewise fine.

Maybe you're thinking of the notorious texture pop-ins? This is quite a
different problem. 

The second video clip I linked to was recorded on a Tahiti GPU in 2016 and was
presumably using radeon and not amdgpu. Probably why my regression testing lead
nowhere.
