padBuffersToMaxVertexAttribStride (Vulkan workarounds) anglebug:4428: Disabled: isAMD
Vulkan considers vertex attribute accesses to count up to the last multiple of the stride. This additional access supports AMD's robust buffer access implementation. AMDVLK in particular will return incorrect values when the vertex access extends into the range that would be the stride padding and the buffer is too small. This workaround limits GL_MAX_VERTEX_ATTRIB_STRIDE to a maximum value and pads up every buffer allocation size to be a multiple of the maximum stride.
