this problem also occurs on adreno devices no matter 7xx or 6xx, while the log from emulator (GameFusion) is not very easy to extract

my friend record a video for demostration
I think according to your log the game seems to be using native Vulkan and not dxvk. That is also what the Steam Proton version launches for me by default. You can try to force d3d11 mode by launching with FNA3D_FORCE_DRIVER=d3d11 or if you want to try OpenGL FNA3D_FORCE_DRIVER=opengl

the broken bloom can be seen from this star wall, looks like many glittering lights.
this bloom is more natural, at least it looks like bloom.
Another thing is the dash shadow looks like a fluffy object.
this is correct one, under Proton w/ the game is XNA variant which use opengl as backend under windows
