Bug Report: Screenshot Not Capturing with Android Compose UI (ModalBottomSheet / Dialog Not Included)

[IntuzSachinN]

Summary

Screenshot fails to capture the full UI when using Jetpack Compose ModalBottomSheet, Dialog and other overlay windows are missing.
When using Gleap’s screenshot capture inside a Compose app, the screenshot does not include UI components rendered in separate windows or overlay layers.

---

Not Captured in Screenshot

The following Compose & Android UI elements do NOT appear in the screenshot:

• ModalBottomSheet (Material 3)
• Dialog (Android / Compose)
• Any UI displayed inside a BottomNavigation nested graph
• Any view rendered using an additional window
  (example: popup layers, dialog windows, surface overlays)

This results in incomplete or misleading screenshots when reporting bugs involving sheets or dialogs.

---

Expected Behavior

Gleap screenshot should capture the entire visible UI, including:

• Bottom sheets (Compose ModalBottomSheet)
• Popups and dialogs
• Overlay UI inside nested NavHost graphs

---

Actual Behavior

Gleap only captures the Activity root window, missing any UI drawn in:

• Another Window
• Compose DialogWindowProvider
• Material 3 ModalBottomSheet internal window layer

What appears:

• App bar
• Main screen content
• Background views

Missing:

• Bottom sheet content
• Dialog content
• Any overlay rendered above the root window

---

Steps to Reproduce

1. Show a Material 3 ModalBottomSheet

ModalBottomSheet(
    sheetState = sheetState,
    onDismissRequest = { }
) {
    Text("Bottom Sheet Content")
}

2. Trigger Gleap Screenshot

Gleap.open()

3. Screenshot Result

• Bottom sheet not visible
• Only background activity content captured

4. Same issue happens with:

Dialog { ... }
