Canvas unresponsiveness and execution lag during mobile diagramming?

Hello everyone,
I have been using Lucidchart for some of my more complex workflow mappings lately, but I’ve run into a frustrating technical bottleneck when working from my tablet. Whenever I am running a series of automated background tasks—specifically when syncing large data sets into my diagrams—the entire canvas interface starts to stutter significantly. It feels like the main thread is blocking during the initial handshake, which results in the whole app hanging for several seconds before I can actually drag a shape or edit text.

I’ve already tried clearing the cache and reducing the number of active layers, but the "micro-freezes" persist during peak execution of the background scripts. I even went through a clean roblox modified setup for my mobile execution environment to see if a more isolated script handler would stop the browser from stalling, but I’m still seeing these intermittent handshake delays that cause the UI to lag behind. It is making it very difficult to stay productive during collaborative sessions when the management tools won't stay fluid and responsive.

Has anyone else here dealt with execution lag or UI thread blocking specifically when using the mobile browser version of Lucid? I’m trying to determine if this is a conflict with how mobile browsers prioritize the canvas rendering versus background JavaScript, or if there is a specific setting I should look at to keep the execution flow smooth. I’d really appreciate any insights or debugging tips from anyone who has managed to keep their high-frequency data pulls from freezing the interface!

Hi ​@ladapo52, thanks for posting in the Lucid Community! To make sure I understand the issue fully and can point you in the right direction, would you mind providing me with the following information so I can take a closer look?

  • What device and version are you using? 
  • How are you accessing Lucid on your device? 

I also recommend checking this System requirements for optimized Lucid performance article  for more details on the best system requirements for Lucidchart and Lucidspark.

Thank you your help and patience! Please let me know if you have any questions.
