切换Filter时工作簿变灰，仅手动刷新可恢复，单工作簿异常

Since you’ve already tried the standard fixes (toggling live/extract mode, restarting Tableau, reconnecting/refreshing the data source), let’s dig into more targeted solutions for this stubborn issue:

• Inspect for corrupted calculated fields or filter logic:
  A broken calculated field linked to your filters could be causing rendering glitches. Try removing custom filters one by one, testing the visual after each removal. If the graying stops, rebuild that filter from scratch using clean, simplified logic.
• Reset the workbook’s cache via packaging:
  Tableau sometimes stores corrupted layout cache data for specific workbooks. Go to Workbook > Export > Packaged Workbook to save a .twbx file, then close Tableau, delete the original .twb, and re-open the packaged workbook. This forces a fresh cache rebuild.
• Check for conflicting dashboard elements or extensions:
  If your workbook uses custom extensions (like third-party visuals) or embedded objects, disable them temporarily. Extensions can interfere with filter-triggered refreshes, leading to grayed-out visuals.
• Copy content to a fresh workbook:
  Sometimes the original workbook’s internal metadata gets corrupted. Create a new blank workbook, copy all sheets, dashboards, and data sources into it, then test the filter behavior again.
• Repair your Tableau installation:
  A damaged install might cause odd, workbook-specific bugs. Use your system’s control panel to find Tableau, select "Repair" to fix corrupted files without losing your work.
