It is indeed curious. Although the Viewport Bound only appears in Replace mode, that value seems to affect Add mode as well. (Should it appear for Add as well?)

I also noticed some messages on the console:

RNA_boolean_get: CyclesRenderSettings.auto_scrambling_distance not found.
RNA_int_get: CyclesRenderSettings.sample_offset not found.

"Should it appear for Add as well?"

  • Emm, i don't think so.
  • That is not what "Add" means. Right?
