Cannot Compile Shader

I am receiving this message when viewing a certain replay. It has never happened when playing normally. I have the latest video card drivers, updates, etc.

Replay:

It happens around 2:03 replay time when observing A site from freecam view(F3). First-person perspective does not trigger the error.

Thanks.
