Blank document is slow to load

Lucidchart is getting so slow even with a new blank diagram. It has become unusable.

I used to spend 2 hours a day on Lucidchart. Now I can’t even edit my current diagrams.

I found the problem. It was the WebGL accelerator. I disabled it and the chart is 100 times faster. Thanks for Gemini. I could not find any bug reporting button on the app. I could not find that information in the help pages.

@richardlemieux it sounds like you’re asking why Lucidchart has become extremely slow, even with a brand-new blank diagram. Since you’re seeing the issue outside of just one large document, it may be related to something other than the diagram itself.

A few things to check:

  • Browser: Try opening Lucidchart in an incognito/private window or a different supported browser to see if an extension or cached data is affecting performance.
  • Cache: Clear your browser cache and restart the browser.
  • Hardware acceleration: If you’re using Chrome, try toggling hardware acceleration in the browser settings and restart.
  • Network/VPN: If you’re on a corporate network or VPN, test from another connection if possible.
  • Performance check: Open the Lucidchart document in another browser/device to see whether the slowdown follows the account or the computer.
  • Large diagrams: For existing diagrams, check whether there are many pages, complex shapes, images, or imported content that could be impacting performance.

Since you mentioned even a blank diagram is slow, could you share:

  1. Which browser and version you’re using?
  2. Your operating system?
  3. Does this happen with all Lucidchart documents or only certain ones?
  4. Are you using any browser extensions or a VPN?

That information should help narrow down whether it’s a browser/device issue, network-related, or something account-specific. If I were to take a guess, I’d probably guess that it had something to do with the VPN since there was a time when I couldn’t access anything on my phone when I used VPN.

Hi ​@richardlemieux, thank you for posting in the Lucid Community, and then for providing the answer and solution for other users to access! Thank you ​@aparrish for those great troubleshooting steps. 

I’m happy to hear that this has been resolved for you, but please don’t hesitate to reach back out if you encounter any issues with this. 

For anyone else who comes across this post, turning off WebGL as ​@richardlemieux recommended might indeed be helpful! WebGL is a rendering technology for web-based applications that uses your device’s graphics hardware to render content faster.  In rare cases, WebGL can cause lines and text in the editor to appear incorrectly. If you experience performance issues with lines or text, turn off WebGL following these steps to see if that resolves the issue
