調査方針
Investigate the InfiniteCanvas control in the repository, focusing on memory management and rendering logic. The crash occurs in ntdll.dll, suggesting heap corruption. Check for recent changes related to #3178. Review the OnDraw or similar methods for potential buffer overflows or use after free. Reproduce the crash with a debugger attached to identify the exact call stack.
