Write color buffer on opengl not working

hello
somehow i face the same problem that using write color render would cause the game crash after a while
and i view the log file and find out that it alert RSX: Bad depth surface pitch given: surface_width=640, format=1, pitch=64, native_pitch=2560

and when i check both write depth render and write color render, the game did't crash, although the FPS is very low..
P.s i am using Eiyuu Densetsu to test
