Additionally, you have the option to mitigate data load by closing panels, disabling volume tools, or closing unnecessary tabs in your browser (if it's active while using the platform).

Chart Flickering Issue

Users may sometimes experience chart flickering on their PCs while using the platform. This issue is often related to the graphics card and its use in rendering the interface.

  1. We recommend updating your graphics card drivers.

  2. If there are no driver updates available for your card, the platform offers a 'Use Software Render Mode' setting. This disables the use of the graphics card and switches to software rendering, which may resolve the flickering.

  3. Regularly check for Windows updates and driver updates. If the issue resolves after updates, you may disable 'Use Software Render Mode' for better platform performance.
