Broken lighting under Midday environment

[canny]

Repro:

1. Go to: http://maps.secondlife.com/secondlife/Fenfarg/4/124/36

2. Wait for things to fully rezz around you

3. Rotate camera around your avatar, to make sure everything around you is rezzed

4. Change environment setting to Midday (the new PBR version)

5. Stand around, and rotate the camera around for 30s or so.

6. Things will go weird black and white, (See Attached Image)

7. Change to any other environment setting like Midday Legacy

8. Change back to Midday

9. After 30s or so, everything will go dark again.

Issue seems to be limited to this specific area. But I have seen similar things happen once in a while in other places around SL, this one however seems to be 100% reproducible.

Reproduced on both Official viewer and Latest Firestorm.
