Content area is distorted when switching to multi-window mode on some Android devices. #2697
Description
Is there an existing issue for this?
- I have searched the existing issues
Current Behavior
- When switching from regular full-screen mode to multi-window (split or pop-up) mode, the webview display area is smaller than the actual window area, with white space appearing on the right and bottom. However, the touch area is based on the full screen area.
- When switching from multi-window mode to regular full-screen mode, the webview area (viewport) is larger than the actual window area, with the right and bottom areas cut off. The touch area is based on the normal display size.
Expected Behavior
The webview should display properly even when switching between multiple windows.
Steps with code example to reproduce
This has nothing to do with code structure.

Operating System, Device-specific and/or Tool
This issue has been confirmed on the Galaxy Fold 7 (Android 16) regardless of whether it's in the unfolded/collapsed state.
There were no issues on the Galaxy Note 10 5G (Android 12).
There were no issues on iPad Mini 6Gen (iPadOS 26).

Additional information
Begin single mode -> shift to multi window mode
Begin multi window mode -> shift to single mode
Reloading the widget restores the display to normal.
It seems like the issue started with Android 12L. Please check if this issue occurs on other devices and leave a comment with your device model and OS version. I wonder if it could be fixed faster.
