Hi ​@kvenkatbe, thank you for posting in the community! To help us narrow down the potential cause of the issue, could you please try the following troubleshooting step?

• Try this in private or incognito window. For help with opening an incognito window, please see this community post (in English).

This Basic Troubleshooting article from the Lucid Help Center also has some helpful steps you can try. 

Please let me know if you see any improvements after trying the steps above, or if you have any questions! 

Hi...Thanks for responding !

I tried opening the same mindmaps in the incognito window (Google chrome) and I still see the issue occurring. Whenever I tried to expand or collapse a node in the mindmap, the diagram becomes unusable (nothing happens when I click on the mindmap). I am unable to use the mindmap if I want to expand or collapse nodes and I had to refresh each time to use it. If required, I can have a screen sharing session and show the issue. It would be great if there is a solution for this problem very soon.

Hi ​@kvenkatbe, thank you for giving that step a try. Could you please confirm if this is happening to a specific document? Does it happen when you try to add mindmap shapes in a new blank document?

If the issue is document specific, can you please share the temporary Support PIN for this document? This will allow me to take a closer look at the issue you’re experiencing.

For more information on generating a Support PIN, check out this Help Center article. This Support PIN doesn’t allow anyone but Lucid Support to take a look at your document, so you are safe to post it here.

Let me know if you have any questions, thank you!

Hi,

Thanks again for replying.

This happens for every mindmap document I create in lucidspark or lucidchart. I have tried with both using blank board and also with templates, this happens for both the cases. I have added the pin for one such document where you want to have a look.

Hi ​@kvenkatbe, thank you for sharing the support PIN! Taking a look at the board you shared, I am able to reproduce the issue when trying to collapse a node with many branches and siblings attached -- is this the same behaviour you are seeing? 

The cause of the issue is likely the size of your mind map as it does appear to be quite large. Utilizing a very large canvas space and having a high number of shapes and freehand drawings on each canvas increases the time it takes to load and update the board when changes are made. If you are working on a very large board, you may consider breaking it into several smaller documents to improve performance.

Could you please try disabling WebGL and let me know if you see any improvements after trying this? This can be done by selecting View > Rendering > Use WebGL and un-selecting this option.

I hope this helps! Please let me know if you have any questions. ​​​​​
