Jetpack Compose version: 2025.01.00

Jetpack Compose component(s) used: Compose Graphics Ui

Android Studio Build: Android Studio Ladybug Feature Drop | 2024.2.2 Canary 6

Kotlin version: 2.0.0

Steps to Reproduce or Code Sample to Reproduce:

When using a GraphicsLayer to modify how a composable is drawn, if the Composable will be drawn to a canvas other than a DisplayListCanvas then the GraphicsLayer.draw call will fail on API < 29. This is something that we've seen while using the facebook-screenshot-testing library for screenshot testing, as it renders the view bitmaps with View.draw() in this manner.

I've attached a sample project to reproduce the issue. Clicking anywhere on the screen on an API <=28 emulator will produce the attached stack trace.

Steps to reproduce:

1. Draw a GraphicsLayer in a Composable's drawWithContent block using drawLayer(graphicsLayer).
2. Try to draw the view to a standard Bitmap backed Canvas.
3. 💥
