Steps to reproduce
- Start Flutter app in WEB WASM mode: flutter run -d web-server --wasm
- Run testing in mobile browser (google chrome 144.0.7559.132, android 12)
- Test my app 1-2 min.
- Throw in console "RuntimeError: operation does not support unaligned accesses".
- After this we also see many runtime errors like:
- "RenderBox.size accessed beyond the scope of resize, layout, or permitted parent access. RenderBox can always access its own size, otherwise, the only object that is allowed to read RenderBox.size is its parent, if they have said they will. It you hit this assert trying to access a child's size, pass "parentUsesSize: true" to that child's layout() in RenderTapRegionSurface.performLayout."
- Out of boundary errors.
- And other types of errors, because of cascade crush
Before crash App works good, without freezes. After this Runtime error - Interface completely freezes, but main thread works good (other business-logic logs system add to console; and our test js-overlay fps counter, what works in JS in index.html entry point, not freezing and works good)
Memory Profiling Analysis of the UI Freeze
In addition to the runtime errors, we have conducted a memory analysis using the Chrome DevTools Memory profiler, which has revealed a strong correlation between the UI freeze and a specific memory allocation event.
Observations:
At the exact moment the application's UI becomes unresponsive, we observe a sudden and significant memory allocation.
-
Large Memory Spike: A SharedArrayBuffer constructor (e.g., SharedArrayBuffer@4299775) abruptly allocates approximately 30 MB of memory. This is a major anomaly, as other object allocations are typically orders of magnitude smaller (usually less than 500 KB each).
-
Persistent Allocation: This ~30 MB memory block is not released and is held for the duration of the freeze. The memory profiler indicates it is retained in the heap.
-
Difficulty with Inspection: When inspecting the heap snapshot, tracing the origin of this SharedArrayBuffer back to our Dart code is challenging. The object's property tree contains low-level, internal references that do not map directly to our application logic. These references include:
backing_store::system / JSArrayBufferData@4320355map::system / Map@414411prototype::SharedArrayBuffer@843133constructor::SharedArrayBuffer()@843109
Hypothesis:
We suspect that the UI freeze is triggered by a low-level operation within the Flutter Web engine (likely the SKWasm renderer) that allocates a large SharedArrayBuffer for a rendering task (such as handling a large texture, complex shader, or render target). A subsequent error, possibly one of the RuntimeError exceptions seen in the console, occurs during or after this allocation, leaving the memory allocated but preventing the rendering engine from completing the frame, thus freezing the UI.
Here heaptimeline dump (you can see when freezed - after 2.3 min of work we have big 30MB SharedArrayBuffer object):

Expected results
App works without total freezing interface
Actual results
App every time get total freezing interface after 1-2 min works

Steps to reproduce
Before crash App works good, without freezes. After this Runtime error - Interface completely freezes, but main thread works good (other business-logic logs system add to console; and our test js-overlay fps counter, what works in JS in index.html entry point, not freezing and works good)
Memory Profiling Analysis of the UI Freeze
In addition to the runtime errors, we have conducted a memory analysis using the Chrome DevTools Memory profiler, which has revealed a strong correlation between the UI freeze and a specific memory allocation event.
Observations:
At the exact moment the application's UI becomes unresponsive, we observe a sudden and significant memory allocation.
Large Memory Spike: A
SharedArrayBufferconstructor (e.g.,SharedArrayBuffer@4299775) abruptly allocates approximately 30 MB of memory. This is a major anomaly, as other object allocations are typically orders of magnitude smaller (usually less than 500 KB each).Persistent Allocation: This ~30 MB memory block is not released and is held for the duration of the freeze. The memory profiler indicates it is retained in the heap.
Difficulty with Inspection: When inspecting the heap snapshot, tracing the origin of this
SharedArrayBufferback to our Dart code is challenging. The object's property tree contains low-level, internal references that do not map directly to our application logic. These references include:backing_store::system / JSArrayBufferData@4320355map::system / Map@414411prototype::SharedArrayBuffer@843133constructor::SharedArrayBuffer()@843109Hypothesis:
We suspect that the UI freeze is triggered by a low-level operation within the Flutter Web engine (likely the SKWasm renderer) that allocates a large
SharedArrayBufferfor a rendering task (such as handling a large texture, complex shader, or render target). A subsequent error, possibly one of theRuntimeErrorexceptions seen in the console, occurs during or after this allocation, leaving the memory allocated but preventing the rendering engine from completing the frame, thus freezing the UI.Here heaptimeline dump (you can see when freezed - after 2.3 min of work we have big 30MB SharedArrayBuffer object):

Expected results
App works without total freezing interface
Actual results
App every time get total freezing interface after 1-2 min works
