# Objective fixes #5946 ## Solution adjust cluster index calculation for viewport origin. from reading point 2 of the rasterization algorithm description in https://gpuweb.github.io/gpuweb/#rasterization, it looks like framebuffer space (and so @bulitin(position)) is not meant to be adjusted for viewport origin, so we need to subtract that to get the right cluster index. - add viewport origin to rust `ExtractedView` and wgsl `View` structs - subtract from frag coord for cluster index calculation
