Can anyone explain this? Is it a compose bug?
println("a: $progress") works normally, but println("b: $progress") will miss following values, leading to UI not updated. progress is the value of float Animatable .

i didn't understand your bug

[Kyant]

The progress is not updated in the graphics layer modifier, but updated in the draw behind and other modifiers

[Kyant]

It's running a progress animation

[tad]

reading a state inside block will only cause the layer properties update without triggering recomposition and relayout.

If progress isn't backed by mutable state, then you should use the other overload:

.graphicsLayer(
    translationX = ...,
    translationY = ...
)

[tad]

I'm noticing that referencing progress isn't marked as a "State read" in your IDE so I think this is the case.

[Kyant]

but when I inline it as animation.value which is a mutable state, the issue still persists
