 ### Resolved issues
 
 - Fixed a crash when running `rocprof-sys-python` with ROCPROFSYS_USE_ROCPD enabled.
+- Fixed an issue where kernel/memory-copy events could appear on the wrong Perfetto track (e.g., queue track when stream grouping was requested) because _group_by_queue state leaked between records.
 
 ## ROCm Systems Profiler 1.2.0 for ROCm 7.1.0
