  • Tile stealing bugfix: Lukas asks for review of bugfix for the new 2.92 tile stealing feature. (T82351)
  • Resumable rendering: Stefan is looking into support for resumable rendering for tangent animation. Particularly for render farm jobs that can be interrupted, which the current resumable chunks feature is not sufficient for.
  • AMD OpenCL hardware raytracing and denoising: design tasks created by Brian. (T82557, T82559)
  • AMD interested in profiling/optimizing split kernel, Brecht created a task with ideas, partially based on discussion in the meeting. (T82583)
