Troubleshooting: Crashes, Missing Fonts, Slow UI

Safe, quick fixes for common Windows issues in Inkscape — no risky tweaks, just practical steps to get you back to work.

Before you start

  • Make sure you're on the latest stable build (see download button on this page).
  • Reboot Windows if you just installed fonts or extensions.
  • Keep your projects backed up before resetting preferences or profiles.

Crashes at launch or opening files

  1. 1 Try a clean profile: Close Inkscape. Rename your user config folder to back it up. Typical path: %APPDATA%\Inkscape. Rename to Inkscape.bak and relaunch.
  2. 2 Disable third‑party extensions: Temporarily move extensions from %USERPROFILE%\\.config\\inkscape\\extensions or %APPDATA%\\Inkscape\\extensions to a backup folder and test.
  3. 3 Problem file? Launch Inkscape first, then use File → Open. If a specific SVG crashes, try File → Import, or open in Outline display mode.

If the crash disappears with a clean profile, re‑enable items one by one to find the culprit.

Missing fonts or text issues

  • Confirm the fonts are installed for your user (double‑click .ttf/.otf → Install for all users).
  • Restart Windows to rebuild the font cache after new font installs.
  • If text renders oddly, toggle Text → Shape → Flowed vs Regular text and test.
  • Try a clean profile to remove corrupted font preferences.

Slow UI, laggy zoom/pan

  • View → Display Mode → switch to No Filters or Outline while editing.
  • Hide heavy layers; simplify paths (Path → Simplify) to reduce node count.
  • Reduce blur/shadows; rasterize effects for export if needed.
  • On HiDPI screens, adjust UI scaling in Preferences for better responsiveness.

Extensions not working

  • Ensure the extension files are placed in the correct directory (user or system extensions folder as above).
  • Remove duplicate copies of the same extension to avoid conflicts.
  • After changes, restart Inkscape. Some extensions appear under Effects → menu entries.

Export PNG fails or is very slow

  • Try exporting at a lower DPI or smaller area, then upscale externally.
  • Disable filters before export to reduce CPU usage.
  • Export individual layers or groups instead of the whole document.

Reset preferences (How‑to)

  1. 1 Close Inkscape.
  2. 2 Open Run (Win+R) and enter %APPDATA%\Inkscape.
  3. 3 Rename preferences.xml to preferences.bak.xml.
  4. 4 Start Inkscape — a fresh preferences file will be created.

If this helps, you can re‑apply your settings gradually.
