Does anyone experience semi-random hangups of a few seconds when a certain composable enters composition?
I think it has to do with an Image with a compose.materialIconsExtended ImageVector (specifically`Icons.Filled.PhotoAlbum`
which is nothing too complicated in terms of its path).

It happens on my physical iPhone 14 Pro and simulators, but typically on a fresh install, afterwards not anymore.
Does not happen on Android or desktop.

Sample composable:

Image(
    modifier = Modifier.fillMaxSize().clickable {
        dropdownState.open()
    },
    imageVector = Icons.Filled.PhotoAlbum,
    colorFilter = ColorFilter.tint(MaterialTheme.colorScheme.onPrimaryContainer),
    contentDescription = "Image",
)

I have a button that toggles it coming in and out of the composition. When the button is clicked, the app hangs for 1+ seconds.

Yes! But i experience them more so on Android, on my iPhone 14 Pro Max it’s fine. But on Android, if i use image bitmaps in a composable, it’s quite laggy. I thought about caching and preloading them in the future, because the drawing cannot be expensive, only the loading can be

Tried today with larger SVGs, on iOS they load instantly, on Android takes a second.

On Android I didn't notice it but typically issues like these went away with R8 obfuscation. But on iOS I didn't try an archive build yet (need a dev account).

@Rok Oblak what do you mean with R8, which settings would i need to tweak so SVG/xml vectors are loaded quicker on Android?
If you sent a github link or so, i could try an archived build on my iphone..

[Rok Oblak]

by R8 I mean to produce a minified release build (or use minifyEnabled=true on the debug build)
it typically makes the app run fast and stutter-free even on a midrange phone
