After switching from Tableau Prep Builder to another application on Windows and vice-versa, you may notice that the font and User Interface elements are suddenly much smaller and blurry.


  • Tableau Prep Builder 2020.1.2


  1. Close Tableau Prep Builder
  2. Navigate to C:\Users\<username>\AppData\Roaming\
  3. Rename the Tableau Prep Builder <Version Number> folder
    • This will essentially force Tableau Prep Builder to re-generate these files, while providing a backup in case this affects performance.
    • If this process causes issues, close Tableau Prep Builder and restore this file to its original name.
  4. Re-launch Tableau Prep Builder.
