Emulator

What steps will reproduce the problem?

1. Load sms, go to delfino plaza.
2. Run backwards and hop in the water.
3. Press the b button several times to dive.

What is the expected output? What do you see instead?
Everything should be colored blue; instead the colors are inverted and
darkened so it looks blackish-red. Looks like a problem with the colors
getting mixed up.

Please use labels and text to provide additional information.
Probably a problem with a pixel shader?

Above water, I get this (debugfast, loglevel 5):
