Emulator

What steps will reproduce the problem?

1. Launch the game and enter a level (happens most consistently on the stage 1 boss - Karuan)

What is the expected output? What do you see instead?
At random times, the graphics will just freeze on screen(no VPS) while the music continues to plays normally. So the emu still going, just no more video.

Dolphin version with the problem? Other Dolphin version without the
problem?
Current revs - r6298

32-bit or 64-bit and any other build parameters?
64

OS version and versions of tools/libraries used?
Win7

Please provide any additional information below.
Using SC JIT or increasing the watermark or using JITIL seems to make the game more stable.
