ARSceneView Compose code getting outofmemory exception #567

[klinis]

When using arsceneview compose component initially it works fine but sometimes if I reopen it many times (it is hidden from compose view with if consensus) or when hiding and reopen app the application crushes with stacktrace:

    onViewUpdated = {
        if (takePhoto)
            takeScreenShot(this, coroutineScope) { bitmap ->
              ....
              
      fun takePhoto(
      view: ARSceneView,
      coroutineScope: CoroutineScope,
      onPictureSave: suspend (Bitmap) -> Unit
  ) {
  
      // Create a bitmap the size of the scene view.
      val bitmap = Bitmap.createBitmap(
          view.width, view.height,
          Bitmap.Config.ARGB_8888
      )
  
      val handlerThread = HandlerThread("PixelCopier")
      handlerThread.start()
      PixelCopy.request(view, bitmap, { copyResult: Int ->
          if (copyResult == PixelCopy.SUCCESS) {
              coroutineScope.launch {
                  try {
                      onPictureSave(bitmap)
                  } catch (e: IOException) {
                      return@launch
                  }
              }
          }
          handlerThread.quitSafely()
      }, Handler(handlerThread.looper))
  }

I only use session object to take a screenshot with the above method given in onViewUpdatedMethod. Did I miss anything? Why it has this behaviour? Thank you very much
