Problem with Mednafen HW core vulkan, lots of ghosting images

Running a readon 390x, using vulkan render at 32x internal res, nearest, pgxp enabled

In ff8 and vagrant story i get lots of ghosting and shaking, ff8 only seems to be in the fire cave while vagrant story is with any fast moving scene the previous scene seems to over lap some how, its very strange, I have tried lowering every setting seems to never go away, anyone have some advice. I thought maybe its vsync but turning that off had no effect. I would take a screen shot but it only screen shots my desktop
