Don't we have a fallback for that now, as long as you're using OpenGL...?

So what does this all mean?

It means that the vulkan driver shipping on many android devices doesn't support an extension required to correctly emulate the graphics techniques used in some games. Metroid prime is likely one of these - try using the "OpenGL" graphics backend instead and see if that fixes it.

There's a workaround path in OpenGL using a different extension that is widely supported, however, so if you reproduce this on OpenGL and not just Vulkan there may still be an issue.

Yes, I use OpenGL, Vulkan makes Metroid Prime look worse. Those screenshots I took are me using Dolphin with OpenGL

Like I said "I found that the revision "dolphin-master-5.0-1650" isnt broken, but as soon as revision "dolphin-master-5.0-1653" came along, it broke it." dolphin 5.0-1650 has the morphball and morphball bomb rendered on my S8, dolphin 5.0-1653 doesn't even though its the same game, same phone and same video backend.

I appreciate you guys for taking your time out of the day to help me, as I know that time is very precious with school and life in general
