This seems to be an OpenGL issue with your distribution. We only directly support *ubuntu-based distributions, and then only when Kdenlive is installed the Kdenlive ppa's. We also support git master versions for experienced users/developers. Please check with the Kdenlive forum and with your distribution packagers.
