Metal Vertex Buffer Crash During Navigation with High Pitch #3029

Open engali94 opened 2 hours ago

engali94 commented 2 hours ago

Describe the bug The app crashes during navigation when using MapLibre Native iOS with specific conditions:

The crash occurs in the Metal rendering pipeline during MTKView draw:

-[MTLDebugRenderCommandEncoder setVertexBufferOffset:attributeStride:atIndex:]:1874: failed assertion `Set Vertex Buffer Offset Validation
index(1) must have an existing buffer.

......

frame #7: 0x000000022c2b20c0 MetalTools`-[MTLDebugRenderCommandEncoder setVertexBufferOffset:attributeStride:atIndex:] + 276
frame #8: 0x0000000103bf3cc8 GPUToolsCapture`-[CaptureMTLRenderCommandEncoder setVertexBufferOffset:atIndex:] + 84
frame #9: 0x00000001048f65c8 MapLibre`___lldb_unnamed_symbol17940 + 44

To Reproduce Steps to Reproduce

  1. Enable follow user course mode
  2. Constantly feed updated location to simulate navigation scenarios
  3. Pinch to adjust the pitch level to around 50 degrees
  4. Observe CPU spike to ~400%
  5. App crashes with Metal vertex buffer error

Expected behavior The map should handle high pitch ranges during navigation without performance degradation or crashes.

Screenshots If applicable, add screenshots to help explain your problem.

Platform information (please complete the following information):

Additional context

The error suggests a vertex buffer at index 1 is being accessed but doesn't exist, indicating a potential issue with buffer management in the Metal rendering pipeline.

Stacktrace

-[MTLDebugRenderCommandEncoder setVertexBufferOffset:attributeStride:atIndex:]:1874: failed assertion `Set Vertex Buffer Offset Validation
index(1) must have an existing buffer.

I suppose you are using MapLibre Navigation iOS?

Can you reproduce this issue with just MapLibre iOS?

louwers commented 2 hours ago

We're not using MTKView...

sorry it was a mistake at my side I meant MetalTools the app is using MapLibre SwiftUI DSL](https://github.com/maplibre/swiftui-dsl) and Ferrostar navigation
