System Information
Operating system: Linux-5.11.0-38-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce RTX 2070 Super/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.57.02

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-10-26 13:07, hash: b8b9023d8c
Worked: Master from a few hours ago

Short description of error
Position pass is no longer anti-aliased (which is great, thanks Brecht), but now gets rendered either much too dark in simple scene and totally "broken" in more complex setups.

Exact steps for others to reproduce the error

  • Open attached blend file:
    Position_Pass_Bug_v01.blend
  • Press F12 an check the position pass.
  • This is how it should look (apart from the anti-aliasing ;) ):
    Pos_Old.png
  • This is how it looks now:
    Pos_New.png

This now looks as if it was just much darker, but the problem goes further. Here's the same with a more "complex" setup:

  • Old master:
    Pos_Old_Complex.png
  • New master:
    Pos_New_Complex.png
