Amber lags quite a bit for me. Switching tabs (home, settings, permissions) takes about 1 second. F-Droid doesn't, for comparison.

Also, before the update with the auto approve for basic actions (maybe solved now), when Amber opens to approve some action and more show up, it lags heavily. It takes a few seconds to update the list. And the confirm button looks a bit deformed.

I'm using an older phone with Android 14 ROM.
