Suyu/Ryujinx issue

So I know that we are years from Switch emulation being around here if ever but does anyone know how to fix an issue I am having with Marvel Ultimate Alliance 3 on either or emulator? On Ryujinx, the graphics suffer intense flickering everywhere that's not the static menus and in Suyu, again outside the menus, the graphics don't flicker but they ARE a solid dark black as if everything is in shadows. Does anyone know of any fixes for either option? I just want to do an all-Symbiotes (and Deadpool) run with Symbiote Suit Spider-Man, Default Venom, Gwenom, and Default Deadpool.
