Android 11, Multi-window mode: Map becomes unresponsive when resizing app

[johan12345]

MapLibre Android Version

11.7.1

Android SDK Version

Android 11

Device

Emulator

What happened?

When using an app with MapLibre Native in multi-window mode on Android 11 (API 30) tablets, resizing the app a couple times causes visual artifacts and/or makes the app become unresponsive. This should not happen.

On newer Android versions (e.g. API 34) it works fine.

Steps to reproduce

1. Install the MapLibre Android Test app on a tablet emulator (e.g., Pixel Tablet) with Android 11 (API 30)
2. Start one of the demos (e.g., Simple map).
3. Bring the app into multi-window/splitscreen mode.
4. Resize the app a multiple times
5. Try to pan or zoom the map

Renderer

OpenGL (choose this if you are unsure)

I have tested this only on the emulator, unfortunately I don't have a physical Android 11 device to test.

In my app I am still using MapLibre Native 10 for compatibility with OpenGL ES 2. If this is fixed, it would be great if it could also be backported to the 10.x.x branch.

Thanks for the report! I think this is worth fixing. I'll ask on Slack if anyone has an Android tablet to try this out with to see if it's also reproducible on a real device.

On a real device with Android 14 (API 34) a community member was unable to reproduce this.

Yeah, on my real tablet with Android 15 it works fine as well. It seems to be only on Android 11 (and maybe older versions?).
