One screen (characterized mainly by an array of `Button`s) of my Compose-only app has become really sluggish on Android 12, most noticeably in the emulator (I tried a Pixel 4a and Pixel 5). I am on Compose 1.1.0-beta02/AS Bumblebee Beta 3, but I tested back to alpha-06 and with prior versions of my app and I only see the issue on API 31, not API 30. (I am running the debug version of my app, like I have been, in all cases.) Are there known performance issues before I try to narrow this down further?
