Just guessing this may be driver related? I do most of my gaming / testing with Vulkan enabled and have no issues with or without the vertex rounding hack turned on. I'm on an AMD card though.

Well, i don´t know if is a Nvidia problem, but i tested all the games i have, and all the games works perfect with vulkan, unless i check the rounding hack box. Only a few games like Goldeneye wii works with that box checked. In the other 99% of cases i got a black screen. And i tested the other backends with the rounding hack, all works perfect. The only problem is vulkan + rounding hack.

I can confirm that vertex rounding option on Vulkan doesn't work (at least on my system: WIndows 10 - Intel e8600 - Nvidia GTX950)

Works perfectly here: Core i7 4800MQ, GTX870m windows 10.

Then this might be related to https://bugs.dolphin-emu.org/issues/10301 which I've been trying to investigate. I even captured a video of the issue, it's on the notes.

Assuming the issue is still the shaders which is worked around by using the GLSL extension, it should be fixed by PR#6111.

Fixed with that PR.
