Hello，
We’re seeing an iPad-specific Launch Screen issue related to multitasking window sizes.
Environment
- Device: iPad (iPadOS 26)
- Device orientation: Landscape
- App is launched in a small window where the app window is portrait-shaped (width < height)
Issue
When the iPad is in landscape but the app is launched as a portrait-shaped small window, the LaunchScreen.storyboard appears to be rendered/layouted as landscape, not matching the actual window geometry. As a result, the Launch Screen content is clipped / partially missing (we see blank/empty area at the bottom during launch). After the app finishes launching, our first view controller uses the correct window size and the UI looks fine — the problem is mainly during the Launch Screen phase.
What we checked
- LaunchScreen.storyboard uses Auto Layout and is expected to adapt to screen/window size.
- This only reproduces when the device orientation and the app window aspect ratio don’t match (landscape device + portrait-shaped app window, or vice versa). When device orientation and window shape are aligned, the Launch Screen displays correctly.
Question
- Is it expected that iPadOS renders LaunchScreen.storyboard based on the interface orientation / size class rather than the actual window bounds in multitasking scenarios?
- If not expected, what is the recommended way to ensure the Launch Screen matches the app’s actual window size/aspect ratio at launch (without using code, since Launch Screen is static)?
- Are there any additional diagnostics or recommended steps to help us investigate and confirm the root cause (e.g., specific logs, APIs/values to capture at launch such as UIWindowScene bounds, interfaceOrientation, size classes, or any guidance on how Launch Screen snapshots are chosen/cached in multitasking)?
Thank you.
