Anton, thanks for your trust! I've created a merge request for VTK in order to use TBB instead of sequential behavior when dealing with parallel code: https://salsa.debian.org/science-team/vtk9/-/merge_requests/4 I would like to do the same for ParaView but the salsa repo is not sync with the current package in unstable. Version 5.9.0-1 and 5.9.0-2 are missing. Should I push them myself to the salsa repo?
