Flickering in 4 player mode - Sonic rides zero gravity

[CrimsonGaia]

title is pretty self explanatory, in Sonic Riders Zero Gravity when playing in 4 player mode, the 4th players screen and exclusively the 4th players screen will flicker nonstop. This is easily reproducible, as it happened with at least 5 others in both netplay and local, all with differing pc builds. Everyone involved was using 5.0-12051
