Hi Patrick, Many thanks for your help. Unfortunately I still get the same issue (segfault) with this new release, except that the gdb and the core file report slightly different errors. Well, this seems to confirm that the issue is probably due to Mesa or Qt5 libraries (how to check?). You probably can close (or suspend) this ticket since there is no more else to do from the kdenlive side but to expect some fix from mesa or qt side. Best regards Christophe Core was generated by `kdenlive'.
