Hello, I wanted to report that the bug is still happening in 0.6.8-1. The error is similar: glxgears: symbol lookup error: /usr/lib/x86_64-linux-gnu/mangohud/libMangoHud.so: undefined symbol: _ZN6spdlog5sinks18rotating_file_sinkISt5mutexEC1ENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEmmbRKNS_19file_event_handlersE
Difference being the appended "RKNS_19file_event_handlersE" at the end. -- Ignacio Vargas
