Description of problem: FreeCAD starts and displays initial screen, but when displaying anything else (e.g. the example engine block) it segfaults Version-Release number of selected component (if applicable): freecad-0.18.4-1.fc31.x86_64 How reproducible: every time Steps to Reproduce: 1. run FreeCAD from commandline 2. click on EngineBlock.FCStd example Actual results: FreeCAD 0.18, Libs: 0.18RUnknown © Juergen Riegel, Werner Mayer, Yorik van Havre 2001-2019 ##### #### ### #### # # # # # # # ## #### #### # # # # # #### # # # # # # # ##### # # # # #### #### # # # # # # # # # # # # # #

Please try this update first, but also worth mentioning is FreeCAD doesn't work well with Wayland yet so try switching to Xorg as well. https://bodhi.fedoraproject.org/updates/FEDORA-2019-fa74042038
XDG_SESSION_TYPE=x11 FreeCAD results in a similar segv , in what looks like Python infrastructure. Using your 0.18.4-2, I see that Wayland doesn't work at all (coredumps with missing GL context). The proffered advice of setting COIN_GL_NO_CURRENT_CONTEXT_CHECK=1 FreeCAD does NOT work. However, it works with XDG_SESSION_TYPE=x11 FreeCAD
