1. if you use the current github master version, it's a known problem: https://github.com/hashcat/hashcat/issues/2083
2. the VRAM max allocation is a driver restriction (or some would call it "OpenCL spec misinterpretation"), we can't do anything against it. on other operating systems as far as I know, CUDA can allocate more for Nvidia cards than OpenCL. The problem is that the driver only allows to make memory allocations of a maximum size, not more
