Hi. I created a dashboard with my Vega visualizations that display the latest data. It's kind of real-time monitoring dashboard so I have to refresh every certain period. When it refreshes every 10 seconds, the heap size of browser increases every 10 seconds so the browser get killed finally. I found that the memory increases only with Vega visualizations, so I think Kibana doesn't dispose Vega visualizations. It's very critical issue for me. I have to do my job with Vega. Is there any idea to prevent the memory leakage? Thanks ---

Hi Could you provide some details about your installation, which Kibana version are you using, which browser. Is it a specific Vega visualization that causes the problem, or a general problem (think you answered it already, it's a general, right)? thx & Best, Matthias ---
