[Hristijan]

my app is a wallpaper app hence drawing a lot of images

[Hristijan]

can we re-open https://youtrack.jetbrains.com/issue/CMP-3862/Crash-on-iOS-GrGpuResourcerelease ?

[Hristijan]

fun MainViewController(
    onAppInitialized: (() -> Unit)? = null,
) = ComposeUIViewController(
    configure = {
        onFocusBehavior = OnFocusBehavior.DoNothing
        parallelRendering = true
    }
) {
    WallHubApp(onAppInitialized = onAppInitialized)
}

could this parallelRendering cause issues, idk?

[zsmb]

@Andrei Salavei perhaps

[Hristijan]

i will also roll out a version without parallelRendering and see if it alleviates crashes pepe cryingq

[Andrei Salavei]

The issue with parallel rendering fixed in CMP 1.11.0-alpha03 - you can try it. Appreciate for the feedback.
