> What is the point of this hardening feature if you got to disable it ?
It doesn't have to be disabled. Most users are saying OsmAnd runs fine for them with the default of hardened_malloc being enabled. There was no need to disable the other hardening features. A subset of users are experiencing slow performance in the OpenGL rendering mode with hardened_malloc enabled. It's likely due to the implementation in the app doing something quite inefficient which hasn't yet been identified. The hardened_malloc configuration in GrapheneOS is heavily oriented to security and has more overhead than the lite configuration. We could offer a performance vs. security mode for it but it usually makes no major difference and has a toggle for any case it does.
