研究方向
Investigate the code in the Command Palette dock where CPU usage is retrieved, likely using PerformanceCounter or similar Windows APIs. The bug suggests that values are being summed across CPU cores without dividing by the number of cores, causing percentages over 100%. Look for related parsing or display logic in the dock's performance monitoring module. Check if there are any existing fixes or discussions in the repository for similar issues.
