Worked on the pcsx2-qt component within the PCSX2/pcsx2 repository, focusing on stabilizing the Debugger user experience by addressing a regression in breakpoint sizing. Applied targeted debugging and UI development skills to revert the default breakpoint size from 4 back to 1, restoring expected behavior for users and aligning with established debugging workflows. The approach prioritized code health by minimizing risk and avoiding unnecessary feature changes, ensuring that the Debugger component remained reliable. Validated the update against typical debugging scenarios to confirm no adverse impact, demonstrating careful attention to user experience and workflow continuity using UI technologies and debugging expertise.
