Thank you for the report. We will try to fix this soon. In the meantime, could you please start the emulator from the console (see the commands below), open the camera app to crash it and attach the output, it might help to figure out what the problem is:
cd /Users/YOUR_USERNAME/Library/Android/sdk/emulator
./emulator -list-avds
./emulator -verbose -avd YOUR_AVD_FROM_PREVIOUS_STEP
if there is a crash report to send, please send it and attach the report id.

We got a crash report (thanks JP): 872e3b20bc34905b. It says EXC_BAD_INSTRUCTION / 0x00000001 and the console also says "Illegal hardware instruction". I suspect the new MacOS brought a new hypervizor which causes this behavior. Haitao, could you please take a look?

We have quite some crashes like this:
product_name="AndroidEmulator" AND crash.Reason="EXC_BAD_INSTRUCTION / 0x00000001" AND cpu.Architecture="arm64"
br...@monzo.com
The most of crashes happen here:
vVertical_Scale_ARGB_8888_Accelerate
vImageVerticalShear_ARGB8888
vImageVerticalShear_ARGB8888
vImageScale_ARGB8888
vRotateClockwise270Degree_ARGB8888_Accelerate2
vRotate_90_ARGB_8888_270Degree_Accelerate2
ap...@google.com
I suspect EXC_BAD_INSTRUCTION happens in vImageRotate90_ARGB8888 and vImageScale_ARGB8888 which are used by webcam on MacOS.

Hi rforzani22, I am sorry for this experience. This bug is my top priority. We expect a fix to be merged within a week. You should be able to download a build directly from our build server (
Description
Jetpack Compose version: I've tested on 1.3.0-alpha01 and 1.2.0-beta03
Jetpack Compose component(s) used: LazyColumn
Android Studio Build: 221.3427.89.2211.8689873
Kotlin version: 1.7.10
Steps to Reproduce or Code Sample to Reproduce:
Context:
We have a rather large (10k+ items) LazyColumn where scrolling (eventually) leads to the application grinding to a halt, constantly trying to free memory. It can't, we just keep getting lots of these:
Background concurrent copying GC freed 51964(1414KB) AllocSpace objects, 6(120KB) LOS objects, 0% free, 190MB/192MB, paused 101us total 1.483sI took at heap dump at this point and basically all of the heap is used up by instances of
SnapshotMutableStateImpl$StateStateRecord.Replace LazyColumn with a RecyclerView (with each item being a ComposeView) and the memory leak is gone. App performance is night and day better.
I've been trying for hours to reproduce this in a trivial sample project and haven't had any luck yet. Raising this anyway just in case you have any ideas about what might be causing it. Obviously this makes LazyColumn completely unusable for us, so we'll stick to RecyclerView for now!
