private var drawInvalidateTick by mutableStateOf(0)

Could be replaced with mutableStateOf(Unit, neverEqualPolicy()).
Though according to this there is an internal bug which I can't tell if it's already addressed.
If not, mutableIntStateOf can be used instead.

private var drawableIntrinsicSize by mutableStateOf(drawable.intrinsicSize)

Can also be replaced with mutableLongStateOf but I'm not sure if it's worth it.
