@cirno I have an old sysyem from feb 2023 and it was working fine though webviews are definitely sluggish. Can't remember if it was better before when I actually used it. I updated to the latest (04/2023) and I do noticed that the system is overall more sluggish. Not really sure what's happening here. I really wish the installer is capable of installing specific version. On the unsupported MutiROM on my Nexus 5, it's possible to specify which version to install so I think it should be technically possible.
