Vulkan is extremely unstable

Android SDK Version

Android 13

Device

Google Pixel 8 and simulator

What happened?

When using the Vulkan version of MapLibre, my app crashes constantly. Every 10 seconds or so even if I'm not on the screen with a map. The stack traces are very short but all are SIGSEGV crashes.

Crashed: null pointer dereference
SIGSEGV 0x0000000000000064

Steps to reproduce

Use Vulkan version of MapLibre

Without reproduction steps we're unable to investigate the issue you are facing.

Please provide more details.

[Vichy97]

Theres not really any more details to give. The logs only show what I posted. They don't give any kind of stacktrace.

@Vichy97 Are you using a particular style?

Are you using a particular feature or API?

Can you try to reproduce it with a simple demo app and share that?

[Vichy97]

It seems to happen with any style. Tried several. My map is using the location api and the scalebar plugin, but nothing unusual other than that. I am running it inside AndroidView within Compose. I'll try to make a minimal repro example.

My guess would be an issue with the Scalebar plugin.

[Vichy97]

Maybe but it's working fine without vulkan. I thought scalebar just rendered a normal android view based on output from the map. I would guess that's not causing native code crashes.

[louwers]

Yes looks like it is not doing anything OpenGL ES related. But maybe it is hooking in some kind of callback that is not yet implemented for Vulkan yet.

Let's confirm it's indeed the plugin. Then we can look into this with a degugger to see what is going on.
