FA-51175 / Raster clipping / Member archive

Multiview clip routing: output view identity · case 05

Results are labeled by viewport ID instead of the view that rendered them.

Member previewVariant 5 · 3 implementations · 10 checks per implementation

Case contract

A draw provides per-view clip sets, active-view bits, primitive view bits, optional viewport routing, enabled viewport clips, and primitive sample coverage. A view renders only if both masks include it. Route entries select the viewport clip while preserving output view identity. A null viewport route suppresses that view; absent route defaults to matching view index. Disabled viewport scissor passes full extent.

Why this case matters

Raster clip state can leak coverage across draws even when every individual region is valid.

This sample comes from the broken implementation of a controlled reproducer.
