csis01 To be clear, are you saying that you see Google Camera being slower after this update regardless of whether you leave the toggle its default enabled state or disable it, and that there's a performance decrease compared to the previous GrapheneOS release?
This shouldn't be the case at all. You mentioned magisk, so I want to make sure if you're running an official GrapheneOS release and not doing anything unsupported. If you can run a proper GrapheneOS release and the above is the case, please open an issue on GitHub about this so that it can be looked into.
