Blink phenomenon in P4U2 (NPHB00708)

need help pls.. P4U2(persona 4...) (NPHB00708) has grapic problem..(only when fight, other features working very well, even FPS isn't problem)
whenever I battle, charaters blink randomly,frequently(but playble)

[spec]
7700k 1070 16gb RAM


[when I set as vulkan]

Blink phenomenon more than opengl (blink with "pink color")

[when I set as open gl]

(1)when I off frame limit
"Doesn't apper intro scene" "but I could skip the intro" so playble
but frame soooo rugged It is quite uncomfortable for actual playing
Though, Blink phenomenon less than opengl (just charctaers are blinking without any color)
(2) when I lock frame limit as 60
I did anything I can do, but intro "couldn't skip" so I can't play at this setting
If I skip the intro, error code apper and crash rpcs3.

F {rsx::thread} class std::runtime_error thrown: GetAddress(offset=0x220dc00, location=0x1): RSXIO memory not mapped
(in file Emu\RSX\RSXThread.cpp:55)

I did anything I could recall ( PPU,SPU, Thread number setting, firmware setting (auto or liblv2,sprx only) ) If there is no soultion for grapic crash, I want to play as openGL "with frame limiter.." what should I do?? any idea would be appreciated
