The only guarantee of the occlusion query type in Vulkan is that it will be zero when no samples pass, and non-zero when any samples pass. Of course, most GPUs implement this by just placing the # of samples in the result and calling it a day. However, this lax restriction means that GPUs could just report a boolean (1/0) or report a value after one is recorded, but before all samples have been counted. MoltenVK falls in the first category - by default it only reports 1/0 for occlusion queries. Thankfully, there is a feature and flag that you can use to force compatible drivers to provide a "precise" query result, that being the real # of samples passed. Should fix ink collision in Splatoon 2/3 on MoltenVK.
