[cmpeguerog]

Describe the bug Dialog layout sqeeze vertically when soft keyboard is being show.

• Compose Multiplatform version*: 1.6.10-beta03
• OS version(s)* (required for Desktop and iOS issues): Ventura 13.6.6
• OS architecture (x86 or arm64): x86
• Device (model or simulator for iOS issues): Simulator iPhone 15 Pro running iOS 17.2, iPhone 12 Pro Max running 17.4.1.

To Reproduce

2. Request focus to show keyboard as soon as the dialog appears in the composition.

Expected behavior Dialog should slide up without squeeze animation.

It's a known issue and there was a try to migrate this - https://github.com/JetBrains/compose-multiplatform-core/pull/1099

The problem is in low-level sync between native view layout and metal layer rendering.

The current workaround is to disable platform layers via

ComposeUIViewController(
    configure = { platformLayers = false }
)

Worked fine, but as a side effect now the user should handle the keyboad when showing dialogs.

@cmpeguerog My problem is something similar to this, but as you can see in the image below, the BasicAlertDialog is below the keyboard.

I have already added the ComposeUIViewController

configure = {
platformLayers = false
onFocusBehavior = OnFocusBehavior.DoNothing
},

In Android

How did you get the dialog to resize correctly?

Another strange thing is that the density of text and component sizes on iOS seems to get bigger.

[cmpeguerog]

@SirFilbido I just added the platformLayers = false.

@cmpeguerog Does your BasicAlertDialog have any settings in the Modifier?
