Android 13 Causes Severe Lag/Jank

I've been testing Android 13 release candidates and Keybase suffers from severe lag/jank while in conversation thread view. This is 100% reproducible for me on a Google Pixel 6 Pro. Most often the issue presents while typing a new message, especially longer messages, but also presents when scrolling a thread with a lot of messages. Often the issue presents within 10-20 seconds after force-closing Keybase and reopening.

Android version: 13 beta 4 (RC)
Keybase version: 6.0.1

Start by reproducing the lag in Keybase 6.0.1 on Android 13 beta 4 using a Google Pixel 6 Pro, focusing on conversation thread view while typing longer messages and scrolling large threads. Done means the severe lag and jank no longer occurs in those scenarios.
