Offset Map Elements flickering during zoom

[JanTie]

Environment

• Android OS version: At least 13-15, probably any version
• Devices affected: /
• Maps SDK Version: 11.7.0 - latest(11.11.0), also affects v11.12.0-beta.1

Observed behavior and steps to reproduce

I have a map in compose on which several elements are shown or offset depending on the zoom level. Since version 11.7.0 the elements seem to flicker while zooming. It seems as if the offset is recalculated and the element is shown at the original position.

Expected behavior

My expectation would be that the elements would not flicker at all and behave comparable to the previous versions.

Notes / preliminary analysis

I have tested this in a sample project and could not reproduce it in versions <11.7.0. Nevertheless, the error is contained in all versions up to today (11.11.0).

Here is the code that i used for the example project in the video:

style.addImage(
    imageId = "image",
    image = bitmap
)
style.addImage(
    imageId = "image2",
    image = bitmap2
)
val source = geoJsonSource("pointSource").feature(featurePoint)
style.addSource(source)
style.addLayer(
    symbolLayer("layer-test-symbol1", source.sourceId) {
        minZoom(14.0)
        iconImage("image")
        iconAllowOverlap(true)
        iconIgnorePlacement(true)
    }
)
style.addLayer(
    symbolLayer("layer-test-symbol2", source.sourceId) {
        iconImage("image2")
        iconAllowOverlap(true)
        iconIgnorePlacement(true)
        iconOffset(
            step {
                zoom()
                literal(listOf(0.0, 0.0))
                literal(14)
                literal(listOf(0.0, -20.0))
            },
        )
    }
)

Short additional info: it seems like our iOS developers face the same issue(a little less extreme but still noticeable) with the exact same versions as stated above. So it seems like this might be connected to some underlying library and not directly connected to android or compose.
