I've been having this weird graphical glitch where the lightshafts have a strange grid of white squares (they seem to match the brightness of the light around them), and it doesn't always happen. It might start in the middle of a play session, and won't go away. Sometimes (often, actually) the glitch is already "on" as soon as I start the game.

As an update, I'm now running November 11's Nightly (2283295) and the bug still happens.

The only time I have ever seen something similar was artifacts from my GPU overheating due to a failed fan.  But even then, the squares were multicolored, not uniform.
