MM-IssueLoc: A Controlled Benchmark for Evaluating Visual Evidence in Multimodal Repository-Level Issue Localization
arXiv cs.AI 6 hours ago
Researchers released MM-IssueLoc, a benchmark containing 652 issue-PR instances across 23 languages to evaluate how well systems locate bugs in code repositories using both text and visual evidence like screenshots and error dialogs. The strongest evaluated systems achieved 38.96% file-level accuracy at rank 5 and 22.45% function-level accuracy at rank 10, showing current approaches remain far from reliable multimodal localization. The benchmark enables future research to measure whether systems actually use visual information to find issues or rely primarily on text-based approaches.
